摘　　要：提出了一种彩色图像背景减除的快速算法。首先对当前待处理的彩色图像进行矢量滤波,并在HIS颜色模型下,利用彩色通道和亮度通道相互独立的特点,选取某一分量与背景图像进行差分运算,消除当前图像背景,最后填充空洞而得到较为精确的前景对象。该算法摒弃了传统上处理多维彩色向量繁杂的矢量运算,而采用优化后的线性运算加快了运算速度。而且不需要复杂的背景建模。实验表明该算法快速、有效。In this paper, an effective algorithm for the color image background subtraction in HIS color space is presented. Firstly, the color images are filtered by a vector median filter, and then the difference image is produced making use of the separate channel feature between color channels (H and S) and light channel (I) , at last the empty holes in foreground object are filled. Due to use linear operation instead of vector operation in multi-dimension color image processing, the operation speed of this algorithm is faster than that of conventional vector method. The experi ment results show that the proposed background subtraction method is more effective and faster.
