具有颜色信息的目标边界直线段特征的提取

Feature extraction of line segment belong to the boundary of target with color information

直线段特征可以给出图像几何形态的重要信息。在视频跟踪的过程中,希望只提取被跟踪目标边界的直线段特征,并且筛选掉背景图像中的直线以及目标中的纹理直线,文中提出在提取的直线段自身属性的基础上附加考虑其两侧的颜色信息变化情况,从而更有效地获得目标的边界直线段特征。

Line segment could give out the important geometry information of a image. In the process of video tracking,in order to retain only the feature of the line segment belong to the boundary of target, while filter out the straight line in the background image or the line belong to the texture of the target, considering not only property of line segment but also the changes of the color information on both sides of the line,thus,the feature of line segment belong to the boundary of target is obtained effectively. Furthermore,it proposes triangular feature on the basis of this article.
