Abstract

The invention discloses a method for correcting color between images. The method comprises the steps of inputting two images including a first image and a second image having a common public area; determining the linear relationship on a color channel between the first image and the second image by respectively acquiring the color average value of the color channel in the common area of the first image and the second image; and correcting the color value of pixels on the full image of the first image or the second image according to the linear relationship. The invention also discloses a device for correcting color between images. The method and the device provided by the invention can solve the consistency problem of illumination and color tone in panoramic image generation, image registration and image fusion, and can be specifically used in picture processing software of PC (personal computer) terminal, mobile phone and tablet PC, with the advantages of stable correction effect and wide application.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for inter-image color correction. Background technique [0002] In image processing applications such as panoramic image stitching and image fusion, the following problems are often encountered: due to different lighting environments and photographing conditions, even the images obtained for the same scene may appear to people's eyes. difference in color. [0003] When the user needs to splice or fuse the above-mentioned images, the difference in color perception of these images cannot be eliminated, and it is impossible to make a large picture with light and shade and consistent hues based on the above-mentioned images. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a method and device for inter-image color correction, which can solve the problems of illumination and tone consistency in panoramic image ...
