MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202444101366 A) filed by Jashna Oza on December 20, 2024, for A System And Method For Identifying Video Clips Representing Photoplethysmogram (ppg) Signal.
Inventor includes Jashna Oza.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: The embodiments herein provide a method and a system for identifying video clips representing photoplethysmogram (PPG) signals. The method for identifying video clips representing PPG signals includes segmenting a video into video chunks of configurable duration, analyzing each frame within the video chunk for detecting the presence of red pixels indicative of blood flow and validating each frame in case percentage of red pixels exceeds a configurable threshold. The method further includes, screening the video chunks by determining percentage of invalid frames within each video chunk, and rejecting video chunks where the percentage of invalid frames exceeds a configurable threshold. The method further includes, identifying blood flow in valid video chunks, extracting one or more time-series signals from valid video chunks and applying signal processing techniques including wavelet matching to the time-series signal. The method further includes, validating the identified wavelets and adjusting parameters for optimising the identification and validation of PPG signals. FIG.1
