Embodiment Construction
[0096] An intelligent segmentation method of a video image target, which adopts the method of alternately carrying out the background model establishment stage and the foreground detection stage, such as figure 1 As shown, a new color space distance measure and a new periodic dynamic background processing method are used in the YUV color space, and the maximum continuous unmatched time length parameter is used to effectively distinguish the foreground and the background in the modeling stage. This method Specifically include the following steps:
[0097] Step 1: Set the frame rate of the surveillance video as fFPS, and the frame number as n, T 1 and T 2 are the periods of the background model building phase and the foreground detection phase, respectively, when 1≤n≤T 1 When f is the stage of establishing the background model; when T 1 f≤n≤(T 1 +T 2 )f, it is the foreground detection stage.
[0098] Step 2: Convert pixel x n =The pixel value of (R, G, B) is converted fro...
