MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202621042907 A) filed by Dr. Babasaheb Ambedkar Technological University, Raigad, Maharashtra, on April 3, for 'line segmentation system for processing handwritten devanagari document images using a mask-based approach.'
Inventor(s) include Snehal Sunil Gailwad; and Dr. Sanjay Laxmikant Nalbalwar.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a line segmentation system and method for processing handwritten Devanagari document images using a mask-based traversal approach. The system comprises an input acquisition unit configured to receive a scanned document image, an image conditioning unit for performing luminance correction, a grayscale conversion unit, a standardization unit, and a skew correction unit configured to align the document based on entropy evaluation. The system further includes a binarization unit, a thinning unit, and a dilation unit for generating a structurally continuous binary image. A row evaluation unit identifies candidate rows corresponding to horizontal line structures, and a mask traversal unit dynamically traces the line by evaluating pixel presence at multiple vertically offset positions within a movable mask window. A line removal unit selectively eliminates pixels corresponding to the traced horizontal line while preserving adjacent character components, including upper and lower modifiers."
