Title:
IMAGE PROCESSING METHOD, DEVICE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/011011
Kind Code:
A1
Abstract:
The present application provides an image processing method, device, and system. The method comprises: parsing a code stream to acquire an encoding mode of a current image block to be reconstructed of a current image, a residual signal of the current image block to be reconstructed, and a pixel of each reference reconstruction image block corresponding to the current image block to be reconstructed, the encoding mode being an original resolution encoding mode or a downsampling encoding mode, and the current image block to be reconstructed corresponding to M reference reconstruction image blocks; determining multiple reference pixels of the current image block to be reconstructed according to the encoding mode of the current image block to be reconstructed and the pixels of the M reference reconstruction image blocks; generating a prediction signal according to the multiple reference pixels; and generating a reconstruction signal according to the predication signal and the residual signal, and reconstructing the current image block to be reconstructed according to the reconstruction signal to obtain a current reconstructed image block. Therefore, the reconstructed image block obtained by a decoding terminal works better.
