Abstract

The invention relates to a gray level image compression method and device, computer equipment and a computer readable storage medium. The method comprises the following steps that: calculating the histogram cumulative distribution function of an initial gray level image to be compressed; extracting the basic layer of the initial gray level image, and obtaining the luminance average value of the basic layer; and according to the histogram cumulative distribution function, the basic layer of the initial gray level image and the luminance average value of the basic layer, obtaining the target compression image of the initial gray level image. By use of the method, image complexity is subjected to simplified processing, and meanwhile, an imported halo is eliminated.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a grayscale image compression method, device, computer equipment and computer-readable storage medium. Background technique [0002] WDR (Wide dynamic range, wide dynamic range) technology is a technology that can display more details in the highlight area and extremely dark area in the same scene at the same time. [0003] At present, in order to display WDR photos (above 12bit) on an LDR (Low dynamic range, low dynamic range) display (8bit) without loss or less loss of photo details, a local compression processing method is usually used, not only considering the individual components of the image The brightness of the pixels, and considering the positional features and the relationship between pixels, the complexity of image processing is high. Contents of the invention [0004] Based on this, it is necessary to provide a gray-scale image compression method, device, ...
