DETAILED DESCRIPTION OF INVENTION
Image Processing (IP) represents a richly layered field dedicated to extracting meaningful insights from visual data through a variety of specialized techniques. Simultaneously, the field of Artificial Intelligence (AI) has expanded into a vast domain of inquiry, enabling intelligent machines to emulate human cognitive functions. Within this expansive AI domain, Machine Learning (ML) emerges as a crucial subset, empowering systems to autonomously derive conclusions from structured datasets, thereby reducing the need for direct human involvement in decision-making. At the core of ML lies Deep Learning (DL), a refined branch that advances beyond traditional techniques, especially in managing unstructured data. DL demonstrates an exceptional ability to attain high levels of accuracy, at times surpassing human performance. However, this capability depends on ample data to train its intricate neural network models, characterized by complex, multi-layered structures. Unlike conventional ML models, DL models have a natural proficiency for feature extraction-an area that historically required intricate manual engineering. This strength stems from the DL architecture's inherent ability to discern relevant features, sidestepping the need for explicit feature engineering. Anchored in the goal to emulate cognitive processes, DL strives to construct algorithms that emulate the human brain's nuanced patterns of learning. In this work, a broad spectrum of deep learning methodologies developed by various researchers is examined within the context of Image Processing (IP) techniques.
This detailed review explores the diverse and intricate domain of Image Processing (IP) methods, encompassing image restoration, enhancement, segmentation, feature extraction, and classification. Each of these domains forms a foundational element in the manipulation and analysis of visual data, advancing our capacity to refine, interpret, and apply images across a wide array of fields.
Image restoration techniques are critical in addressing and rectifying image degradation and distortions. These methods-such as denoising, deblurring, and inpainting-aim to counteract the effects of blurring, noise, and other forms of corruption. By restoring clarity and precision, these approaches establish a foundation for more sophisticated analysis, essential in fields like medical imaging, security, and beyond.
In the realm of image enhancement, the focus shifts to improving image quality through various adjustments. Techniques that modify contrast, brightness, sharpness, and other visual parameters are used to heighten interpretability. This enhancement enables professionals across domains to observe finer details, facilitating well-informed decisions and in-depth analyses.
The exploration continues into image segmentation, an essential process that divides images into meaningful segments or regions. Techniques such as clustering and semantic segmentation enable the identification of discrete elements within images. This segmentation is invaluable in applications such as object detection, tracking, and scene understanding, where it provides the backbone for precise identification and thorough analysis.

Evaluation metrics are essential tools in image processing, enabling researchers and professionals to objectively evaluate and compare different techniques. These metrics provide quantitative benchmarks, allowing for impartial assessments that guide decisions and improvements in the field.
Metrics for Image Preprocessing
Mean Squared Error (MSE)
Mean Squared Error is the average of the squared differences between the actual and predicted pixel values, giving more weight to larger errors. In image preprocessing, MSE highlights discrepancies between the original and processed images, providing insight into restoration quality.

Where MMM and NNN are the dimensions of the image, and I(i,j) and K(i,j) are pixel values at position (i,j) in the original and processed images.
Peak Signal-to-Noise Ratio (PSNR)
PSNR measures image quality by comparing the maximum possible pixel value with the error (MSE) between the original and restored images. Commonly used in restoration, a higher PSNR indicates better fidelity to the original.

Where MAX is typically 255 for 8-bit images, and MSE is the mean squared error between the images.
Structural Similarity Index (SSIM)
SSIM evaluates image quality by comparing structural information, luminance, and contrast. Higher SSIM values indicate closer resemblance between the processed and original images.

Where μx and μy are mean values, σx2 and σy2 are variances, σxy is covariance, and C1 and C2 are constants.
Mean Structural Similarity Index (MSSIM)
MSSIM extends SSIM by evaluating structural similarity across multiple patches of the image and then calculating the mean, making it more robust for localized distortions.
Mean Absolute Error (MAE)
MAE represents the average of the absolute differences between original and processed pixel values, providing a less sensitive measure to outliers than MSE.
Naturalness Image Quality Evaluator (NIQE)
NIQE evaluates the "naturalness" of an image, assessing its similarity to statistical characteristics found in high-quality natural images. NIQE quantifies deviations in luminance and contrast from expected natural statistics.
Fréchet Inception Distance (FID)
FID measures the quality of generated images by calculating the Fréchet distance between feature representations of real and generated images. Lower FID scores indicate closer alignment with real image distributions.
Metrics for Image Segmentation
Intersection over Union (IoU)
IoU assesses object detection accuracy by comparing the overlap between predicted and ground truth bounding boxes. Higher IoU values represent better segmentation precision.
Average Precision (AP)
AP calculates precision across various recall levels, providing a comprehensive score (the area under the precision-recall curve) to evaluate segmentation and detection accuracy.
Dice Similarity Coefficient (DSC)
DSC, also known as the Sørensen-Dice coefficient, is a popular metric for segmentation that measures overlap between predicted and actual segmentation areas, considering both true positives and false positives. DSC values range from 0 to 1, with higher scores indicating better segmentation fidelity.
Average Accuracy (AA)
AA measures the percentage of correctly classified pixels across all classes, providing a straightforward accuracy metric by accounting for both true positives and true negatives across different classes.

Where NNN is the number of classes, and true positive and negative values are computed for each class.
In these metrics enable rigorous, quantitative assessment of image processing techniques, aiding in the improvement and benchmarking of models and methods in a highly nuanced field.
Metrics for Feature Extraction and Classification
Accuracy
Accuracy reflects the proportion of correctly identified instances out of the total cases examined. Although widely applied to balanced datasets, it may be less reliable for imbalanced data, where one class predominates and accuracy alone can mask performance gaps.
Precision
Precision measures the reliability of positive predictions, defined by the fraction of correctly predicted positives out of all positive predictions made by the model. This metric highlights the model's ability to minimize false positives, essential in situations where incorrect positive results can carry a high cost.
Recall (Sensitivity or True Positive Rate)
Recall is a measure of the model's ability to correctly capture all positive cases, calculated as the ratio of true positive predictions to all actual positive instances. High recall indicates the model's effectiveness in identifying positive cases without overlooking any.
F1-Score
The F1-score is the harmonic mean of precision and recall, balancing both metrics into a single score. It provides a more nuanced measure, especially valuable when the model needs to maintain a trade-off between precision and recall.
Specificity (True Negative Rate)
Specificity quantifies the proportion of actual negative instances that are correctly identified as negative by the model. It complements recall by focusing on the model's ability to accurately recognize negative cases, minimizing false positives.
ROC Curve (Receiver Operating Characteristic Curve)
The ROC curve visually displays the model's ability to differentiate between positive and negative cases by plotting the true positive rate against the false positive rate across varying thresholds. The Area Under the Curve (AUC) provides a single-value summary, where a higher AUC indicates a stronger overall performance. This metric is especially informative in binary classification, where the balance between sensitivity and specificity is crucial.
Image Preprocessing
Image preprocessing is an essential foundation in image processing, comprising a series of operations that refine raw images, setting the stage for deeper analysis, interpretation, or further manipulation. This initial phase significantly elevates image quality by mitigating noise, correcting inconsistencies, and highlighting key information, thus enabling more accurate and reliable outcomes in subsequent tasks like image recognition, classification, and analysis.
Broadly, image preprocessing divides into two main areas: image restoration, focused on eliminating noise and reducing blur, and image enhancement, which sharpens contrast, improves brightness, and enriches details within the image.
Image Restoration
Image restoration is a transformative process aimed at reviving the clarity and fidelity of images compromised by distortion or degradation. This process reclaims the visual quality of affected images, restoring details that may have been obscured by acquisition errors, compression, or transmission artifacts. By correcting such issues, image restoration enhances the usability and interpretability of visual data.
Noise represents one of the main challenges in image restoration, arising from unintended pixel variations that obscure or distort image content. Common noise types include Gaussian noise, which is randomly distributed; salt-and-pepper noise, which creates sporadic bright or dark pixels; and speckle noise, resulting from interference patterns. These issues often stem from the image acquisition process or subsequent data manipulations, impairing image quality and accuracy.
Historically, conventional image restoration methods have aimed to counteract degradation through a variety of techniques. Constrained least squares filters and blind deconvolution work to reverse blurring, while Wiener and inverse filters enhance the signal-to-noise ratio. Adaptive mean, order-static, and alpha-trimmed mean filters adapt their filtering approaches to local pixel distributions, while deblurring algorithms specifically counteract motion or optical-induced blur. Denoising techniques, such as Total Variation Denoising (TVD) and Non-Local Means (NLM), effectively reduce random noise while retaining essential details, marking substantial progress in improving image integrity and clarity.
The field has witnessed substantial progress with the integration of deep learning, especially through Convolutional Neural Networks (CNNs). CNNs excel at learning intricate features in images, detecting patterns and subtleties beyond traditional methods. Through training on extensive datasets, CNN-based restoration techniques often surpass the capabilities of conventional approaches by understanding complex image structures and generating optimally restored outputs.
In recent years, Chunwei Tian and Fei provided a comprehensive review of deep network applications for image denoising, targeting various noise types like Gaussian and white noise.

Beyond these, Pang et al. employed an unsupervised model using unmatched noisy images, aligning loss functions with supervised models to achieve competitive results. Hasti and Shin innovated a denoising method for fuel spray images, finding the modified U-Net architecture excelled in MSE and PSNR comparisons. Niresi and Chi et al. leveraged the Deep Image Prior (DIP) framework to achieve robust denoising in hyperspectral images without regularizers, preserving edges while removing multiple noise types. Zhou et al. introduced a sparse denoising model, DNSD, to address challenges in traditional sparse algorithms, successfully managing issues with generalization and data complexity. Meanwhile, Tawfik et al. offered an extensive comparison of traditional and deep-learning-based denoising techniques, including semi-supervised models and performance assessments.
Additionally, Meng and Zhang developed a method employing a dilated convolutional residual network to denoise gray images, demonstrating notable improvement in high-noise scenarios and enhancing visual quality metrics like Structural Similarity Index (SSIM) and PSNR.
In essence, image restoration is an ever-evolving field focused on the reclamation and enhancement of degraded images, setting new standards for quality through the integration of advanced deep learning frameworks. These advancements continue to broaden the field's potential, allowing for greater image clarity and precision across varied applications.

Image Enhancement
Image enhancement involves the process of manipulating an image to improve its visual quality and interpretability, especially for human perception. This technique includes various adjustments aimed at revealing hidden details, enhancing contrast, and sharpening edges, ultimately resulting in a clearer and more analyzable image. The primary goal of image enhancement is to make features within an image more prominent and recognizable, often achieved by adjusting brightness, contrast, color balance, and other visual attributes.
Conventional image enhancement methods utilize a variety of approaches, including histogram matching for adjusting pixel intensity distribution, contrast-limited adaptive histogram equalization (CLAHE) for local contrast enhancement, and noise reduction filters like the Wiener and median filters. Linear contrast adjustment and unsharp mask filtering are also frequently used to boost image clarity and sharpness.
Recently, deep learning approaches have shown tremendous promise in image enhancement. These methods use extensive datasets and intricate neural network architectures to learn patterns within images, enabling restoration and enhancement with remarkable accuracy. Researchers have examined different deep learning models for image enhancement, each offering distinct strengths and limitations.
The study explores innovative techniques, including the integration of Retinex theory and deep image priors in the Novel RetinexDIP method, robustness-enhancing Fuzzy operations for mitigating overfitting, and the fusion of traditional techniques like Unsharp Masking, High-Frequency Emphasis Filtering, and CLAHE with architectures such as EfficientNet-B4, ResNet-50, and ResNet-18. These techniques bolster generalization and robustness.

This method was rigorously compared with several other techniques, including LIME, NPE, SRIE, KinD, Zero-DCE, and RetinexDIP, showcasing its superior ability to enhance image quality while preserving resolution and minimizing memory usage.
Another significant development is the application of deep learning in iris recognition using Fuzzy-CNN (F-CNN) and F-Capsule models, incorporating Gaussian and triangular fuzzy filters. This enhancement step contributes to improved iris image clarity, integrating seamlessly with existing networks and offering a practical upgrade to the recognition process.
An innovative application combines deep learning with image enhancement to improve tuberculosis (TB) image classification accuracy. This method combines Unsharp Masking (UM) and High-Frequency Emphasis Filtering (HEF) with models such as EfficientNet-B4, ResNet-50, and ResNet-18, achieving notable accuracy and Area Under Curve (AUC) scores, highlighting its potential for accurate TB diagnosis.
Another technique addresses impulse noise in degraded images with varying noise densities using a fully connected neural network (FCNN) mean filter. This approach outperforms traditional mean and median filters, especially in low-noise density environments, illustrating the potential of deep learning in noise reduction scenarios. In image deblurring, a complex-valued CNN (CV-CNN) model incorporates Gabor-domain denoising as a prior in the deconvolution model, evaluated using quantitative metrics like Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity Index (SSIM), confirming its efficacy in deblurring.
Furthermore, the pix2pixHD model has been applied to enhance multidetector computed tomography (MDCT) images for accurate assessment of vertebral bone structures, demonstrating the effectiveness of deep learning in enhancing complex medical images for clinical purposes. Another CNN-based LE-net model has been developed for low-light image recovery, particularly useful in driver assistance systems and connected autonomous vehicles (CAV), emphasizing the need for tailored solutions in specific real-world applications.
Deep learning has also advanced Time-of-Flight (ToF) enhancement in positron emission tomography (PET) imaging, using the block-sequential-regularized-expectation-maximization (BSREM) algorithm for PET data reconstruction. This method shows superior diagnostic performance using metrics such as SSIM and Fréchet Inception Distance (FID), reflecting its capability in enhancing PET imaging for diagnostic use.
In another noteworthy method, the Multi-Scale-Stage Network (MSSNet) offers a deep learning-based approach for single-image deblurring. This approach advances prior deep learning-based coarse-to-fine methods, resulting in state-of-the-art performance in image quality, network size, and computation time.
Overall, image enhancement is essential for improving visual quality, whether for human interpretation or subsequent analytical tasks. Combining traditional methods with cutting-edge deep learning continues to push the boundaries of image enhancement and restoration. These advancements have significant applications across various fields, from medical imaging to low-light scenarios, while tackling specific challenges and enhancing current methodologies.
