Then, a multiscale morphology gradient-based watershed segmentation algorithm is introduced to segment the video frame in the spatial domain.
然后，引入基于多尺度形态梯度的分水岭分割算法，对图像进行空域分割。
This algorithm takes local modem both for spatial domain and frequency domain, therefore it is efficient for instable process, too.
这种算法对于时域或频域的考察都采取局部的方式，所以对于非平稳过程也一样十分有效。
The probabilistic data association algorithm is applied in the spatial domain multi resolution frame and target tracking is implemented at the coarse resolution level.
这个算法在空间多分辨率框架下应用概率数据互联算法，在粗分辨率上实现模糊目标跟踪。
