MUMBAI, India, Nov. 7 -- Intellectual Property India has published a patent application (202517094747 A) filed by Hangzhou Hikvision Digital Technology Co. Ltd., Zhejiang, China, on Oct. 1, for 'image decoding method and apparatus, image coding method and apparatus, and device and storage medium.'
Inventor(s) include Ye, Zongmiao; Chen, Fangdong; Wang, Li; and Wu, Xiaoyang.
The application for the patent was published on Nov. 7, under issue no. 45/2025.
According to the abstract released by the Intellectual Property India: "The present invention belongs to the technical field of image processing. Disclosed are an image decoding method and apparatus, an image coding method and apparatus, and a device and a storage medium. The image decoding method of the present application comprises: extracting image residual data or extended residual data from an image code stream, and obtaining a plurality of extended residual groups on the basis of the extracted image residual data or extended residual data; respectively performing residual recovery on the plurality of extended residual groups, so as to obtain an image reconstruction feature corresponding to each extended residual group; performing spatial-domain resolution amplification processing on the image reconstruction feature corresponding to each extended residual group, so as to obtain reconstruction feature data; and performing image reconstruction according to the reconstruction feature data, so as to obtain a reconstructed image block. Since acquired extended residual data is residual data which has been subjected to spatial-domain resolution reduction processing, residual recovery processing performed in groups on the entire group can be implemented at a low resolution, thereby improving the overall residual recovery calculation efficiency, and reducing the time complexity."
The patent application was internationally filed on Mar. 29, 2024, under International application No.PCT/CN2024/084961.
