Abstract

The invention provides a video monitoring image enhancement method based on color migration matching features. The problem of color enhancement under a monitoring video image is solved by using a color migration method according to the characteristics of the monitoring video image and the continuity and stability of the monitoring video image; under the same scene, the color features of the video image with good monitoring image quality are migrated to the video image needing to be enhanced, or the video image color information with more image color information and a block effect is subjected to color migration, so that the video image to be processed is subjected to color enhancement; a Gaussian pyramid is used for extracting feature points of the video image, so that it is guaranteed that the feature points of the videoimage under different scales can be extracted, the videoimage brightness texture is used for restraining the color, the block effect caused by color enhancement of the videoimage is reduced, videoimage information is enhanced while videoimage color enhancement is guaranteed, the image quality of a target person or a vehicle is good, and powerful support is provided for urban comprehensive management.

Description

technical field

[0001] The invention relates to a video surveillance image enhancement method, in particular to a video surveillance image enhancement method with color migration and matching features, and belongs to the technical field of video surveillance image enhancement. Background technique

[0002] With the rapid development of the economy and society, urbanization is getting faster and faster, and the comprehensive management of the city is facing huge challenges. The monitoring methods and monitoring methods for social public events and public areas in large and medium-sized cities are mainly security video monitoring systems. At the same time, with the widespread use of video surveillance systems in areas such as traffic and security, it is increasingly important to enhance image processing in surveillance scenarios and improve target identification information. The effect of the urban security monitoring system is closely related to the image quality collected by...
