基于改进颜色直方图的体育视频Logo检测

In order to implement image matching based on domain color histogram in HSV color space with low dimension and calculation, an improved sub-block domain color histogram is proposed in this paper. This paper divides an image to three blocks to match character of Logo, which contains image space information, and uses the HSV color space in generating one dimensional color histogram in sub-block, then uses this method in sport video logo detection. The result shows method in this paper has great efficiency on some sport videos.
