Claim Text:
1. A method for decoding an image, comprising: determining, by a device of decoding an image, a current intra coding block that uses a constrained intra prediction method among current inter coded frame; determining, by the device, that neighboring coding blocks that are adjacent to the current intra coding block comprise a neighboring inter coding block; updating, by the device, the neighboring coding blocks with an invariable value only if all of the neighboring coding blocks are determined as neighboring inter coding blocks; otherwise, updating, by the device, at least one pixel data in one row or one column of pixel data in the neighboring inter coding block adjacent to the current intra coding block based on at least one pixel data determined from one row or one column of pixel data in the neighboring intra coding block adjacent to the current intra coding block, and updating, by the device, image data in other neighboring inter coding block needs to be updated with the already updated pixel data in the neighboring inter coding block; and decoding, by the device, the current intra coding block based on the updated pixel data in the neighboring inter coding blocks.
