This paper presents a background subtraction algorithm for detecting moving objects from a static background scene using color images.The algorithm is proposed on the basis of brightness distortion and chromaticity distortion in three-dimensional RGB color space,which is able to cope with varying illumination,reflection and shadow problems with low computational complexity.For an image sequence,background frame is first generated using the medium pixel values as background values;then,color images are converted into binary ones according to chromaticity distortion of current-frame pixels from background-frame pixels;at last,morphologic operation and connected component measurement are introduced to solve background disturb problem.Evaluation shows that the proposed algorithm is highly effective.
