Research That Gets Noticed

Innovation is measured not just by ideas, but by the persistence to transform those ideas into solutions that create meaningful impact. Demonstrating this spirit of research and societal contribution, a multidisciplinary team of faculty members from VNR Vignana Jyothi Institute of Engineering and Technology (VNRVJIET) has achieved a significant milestone with the grant of an Indian patent for their invention, “A Restorative Remedial Solution for Leaf Disease Detection Using Convolutional Neural Networks.”

Originally filed and published in April 2023, the patent was officially granted in May 2026, marking the successful culmination of over three years of rigorous research, evaluation, and innovation. The achievement has now received national attention after being featured in The Times of India, highlighting VNRVJIET's growing contribution to research that addresses real-world challenges.

Technology with a Purpose

Plant diseases account for significant agricultural losses every year, often because infections are detected too late. The patented solution developed by the VNRVJIET research team leverages Artificial Intelligence (AI) and Convolutional Neural Networks (CNNs) to identify diseases in crop leaves at an early stage, enabling farmers to take timely preventive action before diseases spread.

The system was trained using nearly 20,000 images of tomato, potato, and pepper plants and is capable of identifying the ten most common leaf diseases with an accuracy of approximately 96%. Beyond diagnosis, the system also recommends suitable pesticides, helping farmers make informed decisions while reducing unnecessary chemical usage and improving crop productivity. According to the researchers, the next phase of the innovation is to make the technology available as a mobile application for easier access by farmers.

Inspired by Real-Life Challenges

The research was led by Dr. Vijaya Saraswathi R, whose inspiration stemmed from witnessing crop failure in her family's farm during childhood due to the absence of timely disease detection. That experience evolved into a research mission to create an accessible AI-powered solution capable of supporting farmers with early diagnosis and improved crop management.

The project represents a successful collaboration across multiple engineering disciplines at VNRVJIET, bringing together expertise in Computer Science, Information Technology, Electronics, and Electrical Engineering.

A Testament to VNRVJIET's Research Excellence

The grant of this patent further strengthens VNRVJIET's reputation as one of India's leading research-driven engineering institutions. With hundreds of patents filed and numerous innovations addressing industry and societal needs, the institute continues to encourage faculty and students to pursue interdisciplinary research that creates tangible impact.

Alongside this work, Dr. S. Pranavanand contributed to patented innovation in automated millet-food technology, extending the institute's applied research into food processing. The innovations received coverage across leading national media, including The Times of India, The Hindu BusinessLine, Eenadu, Sakshi, and YourStory.

The recognition not only celebrates this remarkable achievement but also showcases how academic research can be transformed into practical technologies capable of improving lives. From laboratory research to national recognition, this accomplishment reflects VNRVJIET's unwavering commitment to innovation, excellence, and technology for social good.
