Problems solved by technology

However, in the human visual system, the human eye is more sensitive to the foreground content, so the encoding file using the same bit mode will affect the reconstruction and the reconstructed image will not be effective.

Abstract

The invention discloses an image coding method, a storage medium and terminal equipment. The method comprises the following steps: acquiring an image feature map and a mask feature map of a to-be-coded image; generating a coding feature map corresponding to the to-be-coded image according to the image feature map and the mask feature map; and obtaining a coding file corresponding to the to-be-coded image according to the coding feature map. According to the embodiment of the invention, when the feature map is coded, the image information carried by each channel in the image feature map is determined based on the mask feature map, so that the image information amount carried by each channel in the obtained coded feature map is different, and different bits can be allocated to different channels according to the image information amount during image coding. Therefore, the channel with a large amount of image information occupies a large amount of bits, the image information amount of important image content in the coding file can be increased, and the image effect of the reconstructed image obtained by reconstructing the compressed image is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image encoding method, storage medium and terminal equipment. Background technique [0002] Image coding refers to the technology of representing the original image pixel matrix with fewer bytes. Usually, the image needs to be encoded in order to save storage space when storing the image, or in order to increase the image transmission speed when the image needs to be transmitted. At present, when image coding performs entropy coding on images, it will allocate the same bit for important image content (for example, foreground content, etc.) and non-important image content (for example, background content, etc.) The amount of image information of the content is the same as that of the non-important image content. However, in the human visual system, the human eye is more sensitive to the foreground content, so such encoding files using the same bit mode ...
