Problems solved by technology

Under normal circumstances, the recognition rate of the first method is relatively low, and it is easily disturbed by noise and other factors; while the second method cannot give an accurate description of the color, and at the same time cannot perform color recognition on a target containing multiple colors , a narrow range of application

Abstract

The invention discloses an identification method for mixed colors of targets and relates to the field of computer vision and intelligent video monitoring. The method comprises inputting a target image, converting color space, calculating the color membership degree, determining the target colors, and outputting the target colors. According to the identification method, the color membership degree of each pixel is calculated in hue, saturation and value (HSV) color space to obtain accurate description of the color of each pixel, and the target colors are identified accurately through reasonably integrating the pixels; color identification defects in the HSV space are overcome to some extent; primary and secondary colors of targets can be output, and the mixed colors of the targets are identified; and the identification method is small in calculation amount, wide in applicability, stable in experiment effect and applicable to target color identification of various public places.

Description

technical field [0001] The invention relates to the fields of computer vision and intelligent video monitoring, in particular to a target mixed color recognition method. Background technique [0002] Target color recognition is widely used in the field of intelligent video surveillance. It is an important part of the intelligent analysis system and can be applied to various public places including airports, stations, ports, around buildings, streets, communities and other places. Automatically monitor and judge the color of objects in the scene. [0003] There are two main types of commonly used color recognition methods: the first method is to divide the color into several intervals according to experience, and divide them into each interval according to the value of the pixel points to count and judge the color of the target; the second method is to use SVM. Pan-China ability to identify the target color. Under normal circumstances, the recognition rate of the first meth...
