Title:
IMAGE ENCODING/DECODING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/237475
Kind Code:
A1
Abstract:
The present application provides an image encoding/decoding method and device. The image encoding/decoding method in the present application comprises: obtaining an image to be encoded, the image to be encoded being divided into a base layer and at least one enhancement layer; when feedback information sent by a decoding end is received, determining a reconstructed image corresponding to a frame sequence number and a layer sequence number indicated in the feedback information as a first reference frame, and performing inter-frame encoding on the base layer according to the first reference frame to obtain a code stream of the basic layer; respectively encoding the at least one enhancement layer to obtain a code stream of the at least one enhancement layer; and sending the code stream of the base layer and the code stream of the at least one enhancement layer to the decoding end, the code stream of the base layer carrying encoding reference information. The present application can improve the quality or resolution of a current image frame.
