Abstract

The invention discloses a histogram matching method, a mobile terminal and a computer storage medium, and the histogram matching method comprises the steps: obtaining a first histogram and a second histogram, the histogram comprising a plurality of pixel values and a probability value corresponding to each pixel value; sorting the plurality of pixel values based on the probability value of the first histogram to obtain a corresponding third histogram; sorting the plurality of pixel values based on the probability value of the second histogram to obtain a corresponding fourth histogram; and calculating the similarity between the first histogram and the second histogram according to the third histogram and the fourth histogram and a preset rule. Through the histogram matching method providedby the invention, the two histograms can be quickly matched, and the illumination robustness and the accuracy are 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...
