Problems solved by technology

[0004] However, there are target images of complex scenes that match a single source image to provide limited color
Furthermore, existing algorithms do not transfer the colors of the source image to corresponding regions of the target image in a perceptually aligned manner.

Embodiment Construction

[0028] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation steps of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] The present invention designs a multi-source color image migration method based on a saliency filter, which combines theoretical knowledge of digital image processing, makes up for the defect of limited colors provided by a single color image, and can more effectively realize color migration between color images . Specifically, the present invention comprises the following steps:

[0030] S1. First extract image features, and then perform matching between features to obtain two shape images with high similarity to the shape image. The SIFT feature extraction process is divided into two processes: first extract features offline and store them, and then quickly retrieve them online. The detailed process is as follows: the former f...

Abstract

The invention discloses a multi-source color image color migration method based on a saliency filter, and belongs to the field of digital image processing. According to the color migration method provided by the invention, the defect that the color provided by a single source image is limited is overcome, and color adjustment is performed on the current color image by referring to the specified color image, so that the processed result image has the hue representation similar to that of the color image. Through the method, color migration between the color images can be well achieved, the execution time is short, the image does not need to be labeled manually, and a good color migration effect can be obtained. Compared with the traditional color migration method, the result generated by the method depends on the color image, but is not sensitive to the color distribution information.

Description

technical field [0001] The invention relates to the field of digital image processing, in particular to a multi-source color image color migration method based on a saliency filter. Background technique [0002] With the rapid development of modern society, people have long been surrounded by all kinds of information. Human eyes obtain a large amount of visual information directly or indirectly through the observation of images. Digital image processing technology is an important part in the field of image processing and an important field of computer technology research. Digital image processing technology is the basis of many disciplines, has strong practical value, and is widely used in many fields such as medicine, transportation, media, and education. One of the most common problems in image processing is to change the color of the image to make it the color we need. [0003] From the perspective of the human eye, color is one of the basic characteristics of human per...
