Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0022] figure 1 A color RGB image is shown. As can be seen from the figure, the image is obviously yellowed and the color is distorted. In order to restore the true color in the original scene as much as possible, it needs to be corrected for color consistency. Before implementing it, some clarifications on some variables.

[0023] Color image without color consistency correction X(i,j)=(r(i,j),g(i,j),b(i,j)) T , the corrected image is Where (i, j) represents the spatial position of the pixe...

Abstract

The invention discloses a full-automatic efficient calculation color conformity method. The method comprises calculating the average of respective color channels of original RGB images, calculating the image average through the color average, blending global color and local color characteristics by using the averages and by the aid of the camera color filtering structure and the color tone consistency model to perform color correction on each pixel of each color channel of the images adaptively, and a user can further adjust parameters according to own requirements according to the corrected images to obtain better results. The simulation method experiment result shows that the raised method can obtain a delightful visual effect.

Description

technical field [0001] The invention relates to the technical field of digital equipment imaging and image processing, in particular to RGB color images and the visual enhancement of the color consistency of the corresponding RGB images. Background technique [0002] With the gradual popularization of digital devices that can shoot, more and more consumers use ordinary digital devices to shoot videos or pictures. For users, these digital images record some specific people or events, so they have specific significance. However, for ordinary consumers, it is difficult to obtain professional-level images obtained by professional camera equipment. In many cases, the colors of the scene obtained by different lighting are different. To a large extent, the human eye is able to adapt to these changes in light and accurately identify these colors. The digital equipment used by users to shoot images or videos does not have the same characteristics of adaptive light changes as the h...
