ENCODING AND DECODING METHOD, ENCODER AND DECODER, AND IMAGE PROCESSING SYSTEM

摘要

An encoding method contains the steps as follows: encoding I frame to acquire the first reconstructive image; encoding the reference images from I frame to the recovery point to acquire the second reconstructive image; refreshing said second reconstructive image to acquire the first rebuilding image; and encoding the frame relating to the recovery point with the first reconstructive image and/or the first rebuilding image as the reference images. A decoding method, an encoder, a decoder and a image processing system.
