Problems solved by technology

[0003] However, during the process of conceiving and implementing this application, the inventors found at least the following problems: In the multi-view video coding technology, the loop filtering process (such as the loop filtering process based on neural network) stage is to reduce the distortion of the reconstructed frame , usually using reference frames from different viewpoints at the same time to enhance the reconstructed frame, and the generated enhanced frame is used in the subsequent encoding process, but because the relevant information is not fully utilized in the filtering process, the image block of the reconstructed frame and the reference frame The image blocks cannot be well matched, which affects the quality of multi-view video coding

Abstract

The invention provides an image processing method, an intelligent terminal and a storage medium. The image processing method comprises the following steps of: acquiring first auxiliary information; and processing a first image block corresponding to a first viewpoint according to a reference image corresponding to a second viewpoint and the first auxiliary information. Through adopting the image processing method, the information of the image blocks of different viewpoints can be fully utilized, the distortion of the reconstructed image or the decoded image is reduced, and the coding quality of the multi-viewpoint video is effectively improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to an image processing method, an intelligent terminal and a storage medium. Background technique [0002] Different from single-view video, multi-view video captures the same scene from different perspectives through multiple cameras, which can provide viewers with rich dynamic scenes and real sensory experience. With the development of video compression technology, the research on video coding technology for multi-viewpoint video is gradually deepening. Currently, the 3D-HEVC coding technology proposed on the basis of the video coding standard HEVC (High Efficiency Video Coding, High Efficiency Video Coding) can efficiently compress multi-view video and its corresponding depth data. [0003] However, during the process of conceiving and implementing this application, the inventors found at least the following problems: In the multi-view video coding technology, th...
