A shadow detection approach based on the proposed horizontal and vertical histograms was established. The method firstly constructs the horizontal and vertical histograms and gets the clustering centres of the pixel position in the upper human body, and then two groups of thresholds are chosen. Two initial shadow detection images are gotten based on the two groups of thresholds. Final shadow deletion...
Knowing the background model of a video scenario simplifies the problem of object segmentation and object tracking in the automated video surveillance applications. In this paper, a new algorithm for background model estimation was presented, which is useful in situations where an unobstructed view of the background is not always available. Discovering the true background interval in pixel's intensity...
