Abstract

The invention relates to the technical field of video coding, and discloses an integer motion estimation method for video coding, which comprises the following steps of: calculating a first SAD value of a current block of a zero point according to a central point, and outputting a relative coordinate of the central point as an optimal motion vector under the condition that the first SAD value is smaller than a threshold value; calculating a second SAD value of the current block of the dense area according to the first search point, and outputting the relative coordinate of the first search point as an optimal motion vector under the condition that the second SAD value is smaller than a threshold value; and under the condition that the optimal motion vector is not determined in the current block of the dense region, calculating a third SAD value of the current block of the sparse region according to the second search point, and under the condition that the third SAD value is smaller than a threshold value, outputting the relative coordinates of the second search point as the optimal motion vector. The problems that existing integer motion estimation correlation calculation is long in consumed time and large in consumed storage space are solved.

Description

technical field [0001] The present invention relates to the technical field of video coding, and in particular, to an integer motion estimation method, system and storage medium for video coding. Background technique [0002] With the rapid development of video technology, the amount of information carried by video has increased significantly. As the core technology of video transmission, video coding technology can eliminate redundant information in video, reduce bandwidth pressure and storage cost during video transmission, and reduce the cost of video transmission. In the encoding process, Integer Motion Estimation (IME) is the most complicated part in the encoding process, taking up more than 50% of the entire video encoding time. Currently, in the search algorithm of integer motion estimation, it can be divided into full search. Compared with full search, fast search can save a lot of time and improve coding performance, but it still requires a lot of time and storage c...
