MUMBAI, India, Sept. 22 -- Intellectual Property India has published a patent application (202641105578 A) filed by Saveetha Institute Of Medical And Technical Sciences on September 02, 2026, for A Robust Fingerprint Recognition Framework Employing Adaptive Depth Estimation And Spectral Noise Compensation.
Inventors include Sumesh Mohan; Dr. V. Sheeja Kumari; and Dr Ramya Mohan.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: The present invention relates to a robust fingerprint recognition framework employing adaptive depth estimation and spectral noise compensation to improve biometric authentication accuracy. The framework captures fingerprint data using multi-spectral imaging to obtain both surface and subsurface ridge information. Adaptive depth estimation dynamically models ridge depth variations, while spectral noise compensation suppresses noise caused by skin conditions, sensor artifacts, and environmental interference. The proposed framework ensures reliable and secure fingerprint recognition under diverse operating conditions.
