Abstract

The invention relates to a video image block processing method and a video image block processing device. The method comprises the following steps of: acquiring matching errors between a current template of a current block and reference templates corresponding to more than one estimated motion vector; correcting the matching errors between the reference templates corresponding to a part or all ofthe more than one estimated motion vector and the current template according to the credibility of the estimated motion vector; selecting an optimal matched template from the more than one reference template according to the corrected matching errors; and obtaining a predicted block of the current block according to the optimal matched template, and coding or decoding the current block. By the method and the device, matching similarities between the reference templates corresponding to incredible estimated motion vectors and the current template are reduced, so the probability that the selected optimal matched template is the reference template corresponding to a credible estimated motion vector is increased, and wobble effects are worsened.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, to a video image block processing method and device. Background technique [0002] In video coding, motion compensation inter-frame prediction technology plays a very important role in improving coding efficiency. In the existing video standards, the encoder uses the method of motion search to derive the motion information, which can be related information of the motion vector (Motion Vector, referred to as: MV), for example: the motion information is relative to the spatial motion vector prediction The motion vector difference of the value is encoded into the code stream, and the decoder decodes the motion information from the code stream, and then uses motion compensation technology to reconstruct the image. For example, in the H.264 / AVC standard, the encoder uses a non-standardized motion estimation method to derive motion information, encodes the motion info...
