Abstract

Disclosed is an image coding method, including: determining a coding mode of a coding block; and performing coding on the coding block using multiple coding modes, including performing coding on pixel sample segments in the coding block using one of the multiple coding modes. Further disclosed is an image decoding method, including: parsing bitstream data of a decoding block, and determining decoding modes of pixel sample segments of the decoding block; and performing hybrid decoding on the decoding block using multiple decoding modes, including performing decoding on the pixel sample segments of the decoding block using corresponding decoding modes. The technical scheme described above can fully exploit and utilize the characteristics of each coding image region in the image to improve the image compression performance.
