Abstract: The Camshift algorithm based on color-kernel can effectively track objects in a simple background, but it is easy to be interfered by illumination variation or the similar color object in the background. To improve the algorithms ability to respond to illumination variation, a multi-feature adaptive fusion scheme based on color, shape and texture was proposed. And further improvements have been proposed through modifying feature histogram and setting a reasonable search region to solve the problem of similar background. The experimental results show that the improved algorithm has higher tracking accuracy than traditional algorithm in the scene with illumination variation or similar background.
