MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202531130347 A) filed by Asansol Engineering College, Asansol, West Bengal, on Dec. 22, 2025, for 'non-linear signal modulation framework for motion-stabilized image processing in dynamic environments.'
Inventor(s) include Dr. Sambit S Mondal; Sumanta Karmakar; and Dr. Sujit Goswami.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a Non-Linear Signal Modulation Framework (NSMF) for achieving robust motion-stabilized image processing in highly dynamic environments. The system comprises a motion estimation module (MEM), a non-linear modulation engine (NLME), a temporal stabilization unit (TSU), and a multi-domain fusion layer (MDFL) to effectively mitigate distortions arising from rapid motion, vibration, and non-linear sensor noise. The MEM computes globallocal motion vectors and a jitter coefficient that dynamically regulates the NLME. The NLME applies a hybrid non-linear transformation, specifically a hyperbolic tangent-quadratic-exponential composite function, to reshape pixel-level signals. A temporal stabilization unit performs motion-compensated temporal smoothing, while a multi-domain fusion layer adaptively combines spatial, temporal, and frequency-domain information. The processed data is subsequently reconstructed by an image reconstruction engine into a stable, high-fidelity image."
