MUMBAI, India, May 30 -- Intellectual Property India has published a patent application (202341071190 A) filed by Bharath Institute Of Higher Education And Research, Chennai, Tamil Nadu, on Oct. 19, 2023, for 'an ensemble approach to detect diabetic retinopathy using residual contrast limited adaptive histogram equalization (rclahe) method.'
Inventor(s) include S. Shilpa; Dr. B. Karthik; Dr. S. P. Vijayaragavan; Dr. M. Sriram; and Dr. V. Khanaa.
The application for the patent was published on May 30, under issue no. 22/2025.
According to the abstract released by the Intellectual Property India: "If untreated, diabetic retinopathy (DR), an irreversible disease of the retina brought on by high blood sugar, can cause blindness. In this research, a unique automated method for DR detection is suggested. The Fundus Images (FIs) were preprocessed using Residual Contrast Limited Adaptive Histogram Equalization (RCLAHE), which emphasised the lesions.The suggested methodology intends to address the problem of poor fundus image quality and recognise retinopathy signs. RCLAHE images' fundus-related characteristics are extracted using a weighted, fine-tuned VGG-16 algorithm, and the final recognition outcome is determined using soft-max classification. The suggested network can accurately identify the DR phases, according to experimental results. The proposed method's accuracy level was 95.0%, precision was 91.0%, F1-Score was 90.0%, and recall was 87.0% when evaluated on the Messidor dataset. Our suggested network gets comparable performance when compared to other models."
