Description

Picture processing method and device, storage medium and electronic equipment Technical Field The present disclosure relates to the field of image processing technologies, and in particular, to a picture processing method and apparatus, a computer readable storage medium, and an electronic device. Background With the development of computers, the variety of picture formats is increasing. Among these, there are many compression formats such as GIF (GRAPHICS INTERCHANGE Format ) among the picture formats. Therefore, the need to color down the picture to make the picture conform to the compression format is also becoming a problem to be solved. Currently, this problem is solved using the conventional octree method or clustering method. The traditional octree color reduction is divided into three processes of tree building, tree combination and searching for indexes of corresponding colors. After each pixel value of the image is assigned to the last layer of nodes of the octree through the process, pruning operation is further carried out on the current octree according to the target color number so as to carry out the completed color reduction processing. The tree structure related to the color reduction processing process has the up-down dependence of the branch and leaf nodes, and the color reduction processing process and the clustering method are calculated on a CPU (central processing unit ) in series, so that the consumption of the CPU is too great. In addition, when the problem of color degradation is handled on a mobile terminal such as a mobile phone, the mobile phone is stuck and heated, and the color degradation result is obtained for a long time, which is a serious time-consuming situation.
