Embodiment Construction

[0077] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0078] refer to figure 1 Shown, a kind of image processing method based on improved Codebook foreground detection of the present invention, comprises steps as follows:

[0079] Step 1: convert RGB color space to YCbCr color space;

[0080] In the RGB color space, the correlation between the three components of R, G, and B is very high, which will lead to the fact that, for the same color attribute, the values ​​of R, G, and B will be very scattered under different lighting conditions, and the As a result, in the process of identifying a specific color, it is difficult to determine its threshold and its distribution range in the color space. Therefore, in order to avoid this phenomenon, it ...

Abstract

The invention discloses an image processing method based on improved Codebook foreground detection. The image processing method is characterized by comprising the following steps that an RGB color space is converted into YCbCr color space; a Codebook foreground detection algorithm is improved; and foreground detection is performed by using the improved Codebook algorithm. With application of the method, foreground detection can be greatly performed, the influence of light change on detection can be reduced in distinguishing of the foreground and the background, memory consumption can be reduced and the performance can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of image processing, and specifically refers to an image processing method based on improved Codebook foreground detection. Background technique [0002] With the rapid development of science and technology, intelligent video surveillance technology has been more and more widely used in various fields. The technology involves motion detection, object classification and recognition, object tracking, and behavior understanding and description. Among them, target detection is the premise of subsequent processing such as target classification and recognition, and the quality of its results will directly affect the effectiveness of the monitoring system, and it is an important part of the intelligent monitoring system. [0003] At present, there are many methods for target detection, most of which use adjacent frame difference method, optical flow method, background subtraction and hybrid methods, such as combin...
