Embodiment 1
[0027] Such as figure 1 As shown, this embodiment includes the following steps:
[0028] Step 1) Use the foreground extraction algorithm to separate the foreground and background of the target pedestrian image to obtain the foreground area.
[0029]Step 1 specifically utilizes the document "Stel component analysis: Modeling spatial correlations in image class structure (STEL component analysis: modeling the spatial correlation of image class structure)" (Jojic, N.Microsoft Res., Redmond, WA, USA Perina , A.; Cristani, M.; Murino, V.; Frey, B., 2009.CVPR 2009.IEEE Conference 2009.6.20), this method directly uses the code provided by the author For foreground separation, the specific usage is as follows:
[0030] 1.1) all images in the data set are clustered (the number of clusters is set to 128 in this embodiment);
[0031] 1.2) Compare each pixel point of each image with the cluster center, and use the nearest distance center number as the value of the pixel, so that the in...
