Crop-specific weed identification and morphological classification using deep learning - CNN model
K Karthik Reddy
Weed management is a persistent farm problem, directly affecting the crop yield, resource use efficiency, and farm performance. The conventional methods of weed control are generally time consuming, labor intensive, and non-accurate, resulting in cost and environmental risks. To overcome this, our project proposes an intelligent, AI-based weed classification and identification system specifically for weed identification in accordance with the crop type and morphological features. Machine learning, i.e., Convolutional Neural Networks (CNNs), is employed for the identification of weeds from input images and the provision of resultant control methods, thus encouraging precision and green agriculture practice.
Our proposed system works through a multi-step process: weed images are uploaded by users using a web interface, and the backend CNN model processes the input to determine the type of weed. The model is trained with a large database of weed images pertaining to the cotton crop in order to classify with high accuracy. Based on the classification, the system determines weed features to be searched for and suggests control measures specific to the determined weed and selected crop. If the weed belongs to a class other than cotton or has no associated reference data, the application directly shows control information is not provided. The system also gives multilingual outputs like Tamil, Telugu, Hindi, Malayalam, and English, thus being accessible to more farmers from all over India. The tech stack consists of a Python backend Flask), a CNN- trained specifically for image classification, and a database for reference information on weeds. The frontend is in HTML/CSS, and the interaction with the backend is real-time. The system is efficient, flexible, and easy to handle with the additional advantage of having Docker support in order to provide ease of deployment and scaling. Deep learning gives more accuracy to classification, whereas the morphological and crop-specific approach ensures the advice on weed control is relevant in context.
In short, the project offers an intelligent and practical solution to weed management issues of contemporary agriculture. It minimizes reliance on human identification of weeds and provides accuracy, actionable intelligence that minimizes herbicide usage, maintains crop yields, and maximizes efficiency on farms. The addition of AI and language support also gives farmers the capability to make rational decisions irrespective of the degree of technical knowledge or language choice. As agriculture continues to become more technology-based and environmentally friendly, such intelligent solutions will be the driving force to enhance food production as well as environmental harmony.
