[0043] The present invention will be described in detail below in conjunction with the accompanying drawings. It should be pointed out that the described embodiments are only intended to facilitate the understanding of the present invention and do not have any limiting effect on it.
[0044] figure 1 It is a flowchart of a real-time replacement method for complex backgrounds. According to the flow sequence, the specific implementation process of each step of the method of the present invention is as follows:
[0045] 1. Read in the video stream
[0046] The system first obtains the video stream data. There are two ways to obtain video data: one is the image sequence collected by the camera in real time. The second is the video files collected in advance.
[0047] 2. Background learning, construct a fusion background model
[0048] (21) Learning N-frame image sequence; generally learning 40-80 frames, about 2s;
[0049] (22) Establish a feature background based on brightness informatio...
