This paper proposed a method of kernel density estimation (KDE) to get reliable background, and extract foreground object accurately by the experiment. In order to improve adaptive ability for different backgrounds, historical pixels are used to estimate the probability density of current pixels. Combined with shadow suppression, Hue-Saturation-Value (HSV) color information is used to detect and suppress moving cast shadows. This not only alleviate the pollution of foreground, but also get more reasonable background model and foreground object, and improve the accuracy and robustness of motion detection.
