US Patent Issued to GOOGLE on July 15 for "Sparse matrix representation using a boundary of non-zero coefficients" (French Inventors)

ALEXANDRIA, Va., July 16 -- United States Patent no. 12,363,344, issued on July 15, was assigned to GOOGLE LLC (Mountain View, Calif.).

"Sparse matrix representation using a boundary of non-zero coefficients" was invented by Pascal Massimino (Orsay, France) and Vincent Rabaud (Paris).

According to the abstract* released by the U.S. Patent & Trademark Office: "A sparse matrix representation of image or video data for encoding or decoding uses a boundary of non-zero coefficients within the image or video data. A bounding box encloses each non-zero coefficient within an image or video block. The coefficients enclosed within the bounding box are encoded to a bitstream along with dimensional information usable to identify the bounding box with...
