Embodiment Construction

[0051] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0052] 1. The meaning of color coordination of typical scene fusion images

[0053] The currently generally accepted definition of color coordination is: different color combinations produce satisfactory and pleasant effects, and the color combination is considered to be coordinated.

[0054] When defining the color coordination of visible light and infrared color fusion images in typical scenes, it is necessary to consider its specific application requirements and the color characteristics of typical scene images. One of the main purposes of fusion is to improve target detection. In order to increase the contrast between the target and the background color, the target is usually given a bright color, but it also reduces the color coordination of the entire image. Therefore, the color coordination of the fused image is aimed at the image background, an...

Abstract

The invention relates to a color harmony based color fusion image color quality evaluation method, and belongs to the technical field of image fusion in image processing. The method provided by the invention comprises the following steps of: measuring the similarity of fusion image color of natural scene type of horizon as well as green vegetables with the corresponding typical type of memorized color in human brains and selecting the optimal color degree range of town building images, thus calculating the harmony of three kinds of typical scene colors and scene content; and meanwhile, on the basis of a color combination harmony model, constructing a combination weighting harmony model of color regions with different sizes in the image by taking the sum of the color region areas as a weighting coefficient. Compared with the existing color combination harmony evaluation model, the harmony model calculation result disclosed by combining the two aspects has good consistency with human eye subjective feelings, and the typical scene color fusion image color harmony can be evaluated objectively and effectively.

Description

technical field [0001] The invention relates to a color quality evaluation method of a color fusion image, which belongs to the technical field of color fusion in image processing. Background technique [0002] In recent years, with the development of multi-band image sensor technology, the research on multi-band image fusion algorithm has been paid more and more attention by people. Among them, the color image fusion method of visible light and infrared makes full use of the imaging characteristics of the two bands to color the multi-sensor grayscale image. Fusion to obtain a false-color image that is more suitable for human observation. It can effectively improve the visual photoelectric imaging system's ability to detect and recognize objects in the scene, reduce the false alarm rate and recognition error, and show a wide range of application prospects in situation awareness and target detection. Practical systems and equipment have been obtained successful application. ...
