Abstract

The invention discloses a coloring method, apparatus and device for multiple target areas in a picture, and a storage medium. The method comprises the steps of performing graying processing on a to-be-colored picture to obtain a grayscale picture; selecting a plurality of color standard pictures for performing design of different colors for the to-be-colored picture; coloring the grayscale picturethrough the selected color standard pictures; identifying and segmenting a plurality of colored target areas; and fusing the segmented target areas to the corresponding position of the to-be-coloredpicture. According to the coloring method, apparatus and device, the multiple target areas in the to-be-colored picture are colored through the multiple existing color standard pictures coordinated incolor to change color information of the target areas in the to-be-colored picture, so that a lot of time is saved, the color of the picture are not excessively monotonous, the diversity and flexibility of coloring are realized, and different design requirements are met.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method, device, equipment and storage medium for coloring multiple target areas in a picture. Background technique [0002] In the design of posters, leaflets, etc., it is often necessary to design the color of multiple objects in a picture, but the color design of an object is not purely the replacement of pure colors, but also the relationship between the various parts of the object must be considered. Whether the colors are coordinated or not, it will take a lot of time to let the designer manually design the colors of the various parts of the object. [0003] At present, there is a technology for coloring the entire grayscale image, for example, by giving a color image whose color information is defined by the global histogram and saturation, using the Lab color model through bilinear difference Adjust the color to a quarter of the resolution. Encode each pixel in the quant...
