Embodiment Construction
[0040] In order to make the purpose, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0041] The basic scheme of the present invention is: based on the perspective model, divide the video image sample and the target video image area into image blocks, determine the combination form of the two classifiers, analyze and select the confidence training samples and train each two classifiers respectively, and use channel transmission The model gets the density level that maximizes the posterior probability.
[0042] The present invention provides an embodiment. refer to figure 1 , shows a flowchart of a method for estimating crowd density in a video image according to an embodiment of the present invention, which may specifically include the following steps.
[0043] Step 1: The block analysis unit selects a target area in t...
