Embodiment Construction

[0050] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0051] For an example of the invention see Figure 1 to Figure 4 , the detection and suppression method for the disturbance target includes the following steps:

[0052] (1) Generation of background album:

[0053] Considering that the background changes greatly in the dynamic scene, and its change law within a period of time has a certain degree of randomness, at different nodes in the continuous video frame sequence, the position range, appearance, and gray level of the disturbance target in the background All have a certain degree of fluctuation, and the difference is random. This is a distinctive feature of background interference targets. Create an image set {Img with capacity N 1 ,Img 2 ,...,Img ...

Abstract

The invention discloses a detection and suppression method for a disturbance target. The method includes the following steps of background photo album generation, background photo album updating, background photo album replacement, space-time continuous attribute building, target motion trail establishing and disturbance target judgment. The method can effectively suppress interference caused by random noise, rapid light and shadow changes and background object slight disturbance in a dynamic scene and effectively detect a moving target; an initial motion trail is established for the moving target on a time sequence, therefore, the conditions needed for enabling a foreground target to enter the subsequent identification process are enhanced, the algorithm complexity is lowered, the efficiency of a target identification module is increased, and the accuracy of the target identification module is improved.

Description

technical field [0001] The invention relates to an image processing method in moving target detection and recognition, in particular to a detection and suppression method for disturbing targets. Background technique [0002] The method of segmenting the moving target based on the foreground detection algorithm, and then identifying the moving target through the recognition algorithm is the main way to recognize the moving target under the static camera. The mechanism of screening the candidate moving targets provided by the foreground detection algorithm greatly affects the efficiency and accuracy of the subsequent discrimination process. In many applications such as intelligent video surveillance, road traffic monitoring, and railway pedestrian monitoring, disturbance targets caused by random noise, rapid changes in scene light and shadow, and slight changes in objects bring great difficulties to the recognition process. These types of perturbation targets have the followi...
