Method and device for color editing of natural image with repetitive scene elements

Abstract

The invention relates to a method and a device for color editing of a natural image with repetitive scene elements. The method comprises: preprocessing a to-be-edited natural image by a super pixel segmentation method, so as to divide the natural image into a predetermined number of image sub-block areas; extracting color features and texture features of the natural image, and constructing a feature space vector according to the color features and the texture features; clustering the predetermined number of image sub-block areas according to the feature space vector, so as to locally assign colors to the natural image on the basis of a clustering result; by a global optimization algorithm, carrying out color transfer of the natural image which is already subjected to local color assignment, in order to obtain an image which is a result of image editing. The method and the device of the invention can improve the speed of color editing, effectively keep the consistency of colors of repetitive scene elements, realize editing of different colors of the image sub-block areas with different marks, and obtain rich color editing results.

Description

technical field [0001] The invention relates to the technical field of image editing, in particular to a method and device for editing natural image colors with repeated scene elements. Background technique [0002] With the popularization of digital cameras and digital video cameras and the rapid development of Internet technology, people can easily obtain a large number of digital images and digital videos, which makes people have higher and higher expectations for the convenience and speed of processing tools to meet the needs of digital images. and video editing needs. Therefore, the research on intelligent editing processing of digital images and videos has become a research hotspot in related fields, and the color editing processing technology has attracted much attention of researchers in recent years. [0003] At present, focusing on the three aspects of the function, performance and user-friendliness of color processing technology, researchers hope to provide users...
