Problems solved by technology

Color migration technology provides an effective method for changing the color of an image, but the current color migration method has a big deficiency: the color migration algorithm based on statistical matching is difficult to achieve when the source image and the target image are quite different. Satisfactory migration effect is obtained, so the scope of application is limited; the color migration algorithm based on manual interaction is difficult to achieve automatic batch processing; the color migration algorithm based on image segmentation is more complex, and the migration effect of the edge area is not ideal

Embodiment Construction

[0036] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0037] A kind of color image color migration method provided by the present invention comprises the following steps:

[0038] Step 1: Build an intermediate image;

[0039] Extract the color features of the reference image (hereinafter also referred to as "color image"), construct an intermediate image based on these color features, and use this intermediate image to replace the original reference image for color migration;

[0040] Its specific implementation process includes the following sub-steps:

[0041] Step 1.1: Color Classification;

[0042] Traver...

Abstract

The invention discloses a color image color migration method, which is a color migration method that adjusts the tone of the current color image with reference to a specified color image, so that the processed output image has a tone expression similar to the reference image. The process includes constructing an intermediate image , mesh division processing, color migration processing. Through this method, color migration between color images can be better automatically realized without manual intervention. Especially in the case where the tonal difference between the image to be processed and the reference image is large, a better color migration effect can be obtained.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a color migration method for a color image. Background technique [0002] In image processing, it is often necessary to change the color of an image. For example, special effect processing and scene transformation of images in the film industry, beautification and rendering of characters in the photography industry, understanding and recognition of three-dimensional scenes in robot vision, image restoration and scene simulation reproduction in the military security field, etc. Color migration technology provides an effective method for changing the color of an image, but the current color migration method has a big deficiency: the color migration algorithm based on statistical matching is difficult to achieve when the source image and the target image are quite different. Satisfactory migration effect is obtained, so the scope of application is limited; the ...
