Abstract: A method including acquiring dimension information of an image; determining dimensions of texture memory corresponding to the image based on the dimension information of the image; and dividing the image into multiple image blocks based on the dimensions of the texture memory, and storing the multiple image blocks obtained after the division in the texture memory according to a preset storage rule. The methods and apparatuses for storing an image in texture memory save the memory capacity and increase the image processing speed.

Abstract: The present disclosure provides a forward multiple-hypothesis encoding/decoding method of an image block. In this method, motion information of a current block including two forward reference frame indexes and two motion vectors are selectively encoded into a bit-stream based on a current encoding mode. The motion information which is not encoded into the bit-stream is derived at a decoder by a predefined rule. This method sufficiently utilizes correlation within motion information of an image block and correlation between the motion information of the current image block and that of an adjacent image block.
