Method for replacing color of image based on color harmony

Abstract

The invention belongs to the technical field of image processing, and particularly relates to a method for replacing a color of an image based on color harmony. The method comprises the following steps: firstly, carrying out online crawler on an online website Colorpalettes to obtain all pictures as a data set; performing unsupervised segmentation on each image according to colors to obtain an initial segmentation image, an initial color block type of the initial segmentation image and the number corresponding to each color block; secondly, optimizing the initial segmentation map, the types of the initial color blocks and the number corresponding to each kind of color blocks; segmenting and optimizing the input image, matching a proper color block combination in a database, and giving three color replacement schemes; and finally, optimizing the color lump combination obtained by the three color replacement schemes according to the artistic theory of color matching, and completing color replacement on the original image. The method can adapt to images of any number of color themes in a scene.

Description

technical field [0001] The invention belongs to the technical field of image processing, in particular to a method for re-coloring an image based on color harmony. Background technique [0002] Beauty is an indispensable part of people's daily life. The beauty of color always surrounds people's mood and makes people feel aesthetically pleasing. The beauty of design lies in the combination of form, color and material. However, at the moment of viewing the work, the first thing that attracts the eye is the combination of colors, which is the harmonious and beautiful form of colors. [0003] Color Palettes is an old color matching website that has existed for a long time.

However, the image processing operation similar to color migration does not consider the harmony of the combination of colors, and does not refer to the artistic theory of color combination, and directly replaces the original image with ordinary color based on experience.

Even if some people later studied the harmony of the combination of color blocks, they were all under the premise of fixing the number of color blocks, and did not consider the proportion of each color block

However, there is no research on the spatial position layout of colors. Similar studies only count the frequency of colors in a certain direction based on probability. Although this method can calculate the color possibility of some directions, it is only a large range. The following possibilities are not aimed at the inherent color premise of the scene or the rest of the original image, and cannot give a more reasonable color recommendation
