MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541124508 A) filed by Vishnu Institute Of Technology, Kovvada, Andhra Pradesh, on Dec. 10, 2025, for 'adaptive switching median filter for impulse noise removal in images.'
Inventor(s) include B Prudhvi Raj; and K. Kiran.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to an adaptive switching median-based filtering system for removing impulse noise from corrupted digital images. The system extracts a local neighbourhood window around each pixel and employs a rank-based noise-detection criterion to determine whether the centre pixel is corrupted. Only pixels identified as noisy are replaced, using a median or rank-ordered statistic computed exclusively from uncorrupted neighbouring pixels, thereby preserving edges and fine image details. An adaptive fallback mechanism ensures stable restoration under high noise densities where few uncorrupted pixels are available. The invention provides superior denoising accuracy and structural preservation compared to traditional median and earlier switching filters, making it suitable for real-time and high-precision imaging applications."
