Abstract

The present application discloses a histogram matching method, a mobile terminal and a computer storage medium. The histogram matching method includes: obtaining a first histogram and a second histogram, wherein the histogram includes a plurality of pixel values ​​and each pixel The probability value corresponding to the value; based on the probability value of the first histogram, a plurality of pixel values ​​are sorted to obtain the corresponding third histogram; based on the probability value of the second histogram, a plurality of pixel values ​​are sorted to obtain A corresponding fourth histogram; calculating the similarity between the first histogram and the second histogram according to the third histogram and the fourth histogram according to preset rules. Through the histogram matching method of the present application, two histograms can be quickly matched, and the robustness to illumination is strong and the accuracy is high.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a histogram matching method, a mobile terminal and a computer storage medium. Background technique [0002] Both the target tracking and recognition problems in the intelligent monitoring system will encounter the similarity measurement problem. The target tracking process needs to compare the similarity of the extracted target between two frames of images, and then judge the identity of the target between frames to realize the target correlation between frames. The target recognition problem based on image features is more directly applied to the similarity measure, and the target classification is realized by judging the similarity between the extracted target and the template. [0003] In the process of target tracking and target recognition based on images and videos, when performing histogram matching, the similarity measure calculation is directly applie...
