Description:A METHOD TO IDENTIFY LEAF CONDITION OF GRAPE AND POMEGRANATE PLANT

FIELD OF THE INVENTION
The present invention relates to electronic data processing, and more particularly, relates to image processing methods and systems to analyze the condition of plant or plantation, particularly grapevine or pomegranate plant or plantation.

BACKGROUNDOF THE INVENTION
The current methods for detecting leaf diseases in agriculture primarily rely on manual inspections conducted by experienced agronomists or farmers. These traditional approaches are labor-intensive, time-consuming, and prone to human error, especially when dealing with large-scale farms. Several technologies and methods have been introduced to improve the efficiency and accuracy of disease detection.

US20180120399A1outlines a method for detecting plant diseases using machine learning algorithms applied to image data. However, it does not specifically address grapevine or pomegranate diseases, nor does it incorporate a real-time cloud-based solution as proposed in this invention. Further, WO2019204011A1focuses on general plant disease identification using CNN models but lacks specificity for grapevine and pomegranate plants. The approach to preprocessing and the segmentation methods differs from the techniques used in present invention.

However, most models focus on a limited range of crops or diseases and often lack scalability for broader use in diverse farming environments. These are generally limited by the database they rely on, offering lower accuracy compared to newer, more robust models.
Despite these advancements, there is still a gap in developing a comprehensive, scalable, and highly accurate system specifically tailored to grapevine and pomegranate leaves, which are vulnerable to specific diseases that require targeted intervention.

OBJECT OF THE INVENTION
The objective of the present invention is to develop a reliable CNN-based (convolution neural network) system for accurately identifying state of grape and pomegranate leaves through image analysis, ensuring high performance across metrics like accuracy, precision, recall, and F1 scores.


SUMMARY OF THE INVENTION
The invention presents an automated system for detecting diseases in grapevine and pomegranate leaves using machine learning and image processing. High-resolution leaf images are captured and analyzed by a neural network to identify and classify specific diseases. This method reduces the need for manual inspections, making it a scalable solution for both small and large farms. The system, accessible via a mobile app or farm management platforms, enables early and accurate disease detection, promoting timely interventions to improve crop health and yield. With an accuracy of 94.56%, the system has shown promising results, potentially reducing manual labor and enhancing sustainable farming practices by minimizing pesticide use. The invention offers commercial benefits such as increased crop yield, affordability, and global market potential, and could be provided as a subscription-based service. It is a practical, cost-effective tool for modern agriculture, designed to support sustainable and high-quality farming.

Analysis:
In the present invention, the analyses as represented in table 1, cover a variety of crops and diseases, such as potatoes, tomatoes, and rice; however, the present invention particularly focuses on pomegranate and grape diseases. This focus makes the instant invention distinct, as these crops are less commonly studied in disease detection research, indicating a potential novel contribution to the field. The system of the present invention has accuracy varying in the range of 85 to 98% demonstrating the effectiveness of the system in analyzing leaf condition.
Many of these studies rely on Gray-Level Co-occurrence Matrix (GLCM) for texture-based feature extraction, a traditional technique in image processing. In the present invention, utilizes convolution neural network (CNN) approach which doesn't require manual feature extraction. CNN learns the relevant features directly from the images, which is a significant advantage over techniques that depend on predefined features like GLCM. This allows our model to capture more complex patterns within the image, which are essential for accurate disease detection.
The classifiers in table 1 primarily include SVM (Support Vector Machine), K-means, ANN (Artificial Neural Network), RF (Random Forest), and FLANN (Fast Library for Approximate Nearest Neighbors), which are traditional machine learning methods. These often require predefined features and therefore more manual processing. In the present invention, the use of CNN directly processes the image data and performs both feature extraction and classification in one end-to-end model, making the approach more streamlined and potentially more robust for complex disease patterns.
The model in the present invention having an accuracy of 95.40%, is competitive with, and in many cases surpasses, the accuracy of other studies listed in the table 1. For example, it outperforms studies on crops like potato (92%, 84%, 79%), cotton (94%), tea (93%), rice (89%), and apple (91.7%). Although some studies on pomegranate from 2017 report slightly higher accuracies (98.48% and 96.77%) using combinations of SVM and MTS (Multi-Threshold Segmentation) but it consumes more time as compared to the method in the present invention, as feature training is in build in CNN, the current CNN-based approach offers an efficient and powerful solution that's easier to implement and scale, as CNNs are well-suited to capturing image-based patterns without manual feature engineering.
Table 1 shows the results of crops and diseases with accuracy.
