Problems solved by technology

The current main method of color cast detection of the main image is to perform color cast detection in the RGB space, but the RGB space has the characteristics of being unintuitive, uneven, and device-dependent.
Therefore, it cannot better meet the needs of large-scale security intelligent operation

Embodiment Construction

[0018] Such as image 3 shown.

[0019] The function of the present invention is based on the latest OpenCV library. OpenCV is an abbreviation for "Open Source Computer Vision Library", which is an open source computer vision library from Intel. It consists of a series of C functions and a small number of C++ classes. It can realize many general-purpose algorithms in image processing and computer vision, and can be used to deal with common problems in the field of image and video. It mainly involves the following aspects:

[0020] (1) CvCreateGaussianBGModel-Gaussian background modeling;

[0021] (2) CvCvtColor-color space conversion;

[0022] (3) cvCreateHist - create a histogram;

[0023] (4) cvCalcHist-calculate histogram;

[0024] In the present invention, through the function cvCvtColor, the frame image obtained by input can be converted from RGB space to HSV color space;

[0025] The function cvSplit is used to decompose the HSV color space of the image and extract...

Abstract

The invention provides a novel method for detecting image color cast by a color saturation detecting technology. Based on a color cast detecting algorithms of color saturation detection and application thereof in intelligent security, the method can effectively judge whether color cast is generated, thereby realizing intelligent video monitoring and intelligent judgment.

Description

technical field [0001] The invention belongs to the field of image and video, and particularly relates to the use of color space conversion and cumulative histogram algorithm in color cast detection, and the application of the method in fault diagnosis system. technical background [0002] With the rapid advancement of the safe city project across the country, the infrastructure of the video surveillance system has begun to take shape. More and more, relying on human eyes to check the fault screens one by one is very inefficient, so the importance of intelligent video fault diagnosis is becoming increasingly prominent. [0003] Image color cast detection is a key diagnostic item in video fault diagnosis. At present, the main method of color cast detection of the main image is to perform color cast detection in RGB space, but RGB space has the characteristics of unintuitive, uneven, and device dependence. Therefore, it cannot better meet the needs of large-scale security in...
