Abstract

The invention provides an image coding method and device, a computer readable storage medium and electronic equipment, and relates to the technical field of image processing. The image coding method provided by the invention comprises the following steps: determining an image mapping table corresponding to a to-be-coded image based on the to-be-coded image; determining a plurality of coding unitsof the to-be-coded image; determining offset quantization parameter sets corresponding to the plurality of coding units based on the image mapping table; and performing an encoding operation on the plurality of encoding units based on the offset quantization parameter set. According to the invention, the problem of poor visual effect caused by an obvious demarcation area between the region of interest and the non-region of interest of the image in the existing image coding technology is solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image encoding method, device, computer-readable storage medium and electronic equipment. Background technique [0002] In some image application scenarios or video application scenarios including image frames, some specific regions of interest in the image need to be focused or processed, for example, regions in the image that include facial information. [0003] In the prior art, in order to focus on or process the ROI of the image, the ROI is usually framed in the form of a rectangular frame, and the image quality of the framed ROI is improved. However, due to the significant difference between the image quality of the ROI and the image quality of the non-interest area, there will be an obvious boundary area between the ROI and the non-interest area of ​​the image, which will cause a visual block effect. The user experience is extremely poor. Contents of...
