MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202617050583 A) filed by Interdigital Ce Patent Holdings, Sas on April 21, 2026, for Differential Quantization-Constrained Correction Filter.
Inventors include Le Pendu, Mikael; De Lagrange, Philippe; Pereira Da Silva Santos, Joo Miguel; and Chen, Ya.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: A method is disclosed for correcting an image block, comprising: A reconstructed image block is filtered (S1702) to obtain a filtered image block. A block of difference transform coefficients is obtained (S1704) from the filtered image block and another image block. A correction function is applied (S1706) on the block of difference transform coefficients to obtain a block of corrected transform coefficients. The block of difference transform coefficients is subtracted (S1708) from the block of corrected transform coefficients to obtain a block of correction coefficients. The block of correction coefficients is inverse transformed (S1710) to obtain a correction block. A corrected filtered image block is obtained (S1712) based on the correction block.
