| 摘 要： | 提出了一种基于边缘检测的时空视频对象分割算法。首先提出一种基于高阶统计量的帧间差分图像处理方法,然后运用边缘检测得到空域分割结果和用累计差分与对称差分得到时域分割结果,综合时空域分割结果得到运动目标的边缘,最后对边缘图进行区域填充与数学形态学处理,得到运动目标掩模图像。实验结果表明本文算法能够得到较准确的分割结果。

| Abstract: | A spatial-temporal segmentation algorithm based on edge detection for video object segmentation is proposed in this paper.At first,a method of processing difference frame image based on higher order statistic is proposed.Edge detection is used to obtain the spatial segmentation result.Symmetry differences and accumulative differences are used to obtain temporal segmentation result.The spatial-temporal result is used to get the moving edge map.The next step is filling the regions of the moving edge map,followed by applying morphological, and then the mask of video object is obtained.Experimental results show that this algorithm can give accurate object segmentation. |
