Embodiment Construction

[0067] Since the images in the monitoring often cause false alarms due to various uncertain factors, such as using surveillance cameras to monitor intrusion in a specific space, when there is any change in the space, the pictures captured by the camera will change, so Alarm information is generated, but it is difficult to avoid the problem of being misjudged as a suspicious object due to changes in light, shadow and brightness. The present invention discloses a comparison processing system and method using image color information, and includes an image classification method, especially using Color Space Transformation (Color Space Transformation) to convert the color space of the original image, and by only Color information is retained as the basis for image comparison to eliminate problems that may cause misidentification.

[0068] Among them, the original chromaticity space of the image can be a red-green-blue chromaticity space (RGB color space), but it contains color valu...

Abstract

The invention discloses a processing system, a processing method and an image classification method using image color information. According to a preferable embodiment, continuous images comprising a set reference image and a follow-up image are captured firstly for executing color space conversion, especially, the original color space of the image is converted into a color space of color- saturation-luminance; and the color information is taken as the basis for judging the change of a specific object, and the matching degree is calculated according to the color information of the object in the reference image and the follow-up image so as to judge the particular occurring object.

Description

technical field [0001] The present invention relates to a comparison processing system and method using image color information, especially using color space conversion, and only retaining color information as the basis of image comparison, so as to eliminate the problem of possible misidentification. Background technique [0002] Intelligent Video Surveillance (IVS) system is a closed-circuit television (CCTV) network, console monitors and security personnel. The intelligent video surveillance system under active development can perform image characterization, difference comparison and other image processing processes on the captured images through digital image analysis, find out moving images or analyze meaningful information, and then achieve automatic monitoring. Tracking, judging, and assisting security personnel to find suspicious objects. [0003] In the known technology, there is a monitoring mode that uses closed-circuit television recordings to cooperate with sec...
