Image processing method, method and apparatus for encoding and decoding

Abstract

An image processing method, encoding / decoding method and device, mainly comprising: obtaining image, camera parameter information and object depth information of at least two views; and carry out updating process on image of at least one video according to the image, camera parameter information and object depth information of at least two videos. Embodiment of this invention can carry out updating process on image of video to be updated according to obtained camera parameter of image and object depth information, in order to obtain expected image during encoding or decoding process, reduce encoding bits of image to be updated, reduce calculation load for encoding and decoding.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image codec processing technology. Background technique [0002] In the technical field of multi-view image encoding and decoding, it is often necessary to use a reference image to perform encoding and decoding processing on a current encoding and decoding image, so as to improve encoding and decoding performance. However, in the process of implementing the present invention, the inventors found that in the prior art, when performing inter-view prediction, the images of the reference views are not optimized but are directly used as reference images in the encoding and decoding process. This implementation method still needs to use more bits for encoding some uncritical or unimportant video images, and also occupies more encoding and decoding resources. [0003] In addition, for the case of camera movement, after the camera moves, the first few frames of image...

AI Technical Summary

Problems solved by technology

This implementation method still needs to use more bits to encode some uncritical or unimportant video images, and it will also take up more encoding and decoding resources.

[0003] In addition, for the case of camera movement, after the camera moves, the first few frames of images captured can only refer to each other with the images captured before the camera moves

However, in the process of implementing the present invention, the inventor found that in the prior art, since the images before and after the camera movement may be quite different, when the images before and after the camera movement are referred to each other, the prediction effect will be poor

In this case, the original resolution or size of the image that is not closely related to the front and back content is still encoded, which will also occupy more bits, affect the encoding efficiency, and also occupy more encoding and decoding resources.
