This article proposed a color image background difference based on the HSI(Hue-Saturation-Intensity) model,this algorithm fully considered the relations between H,S and I.According to H and S component was independent with I component mutually,it built a new background brightness information by utilizing H and S component.According to the luminance information,the study used the dynamic threshold value to withdraw the precise prospect object.This algorithm has high speed and effectiveness,and it also has the strong robustness to the noise and the change of light.
