space smoothing

As for the existence of the shadow of the human body and inanity, this article makes shadow detection and elimination by using color space conversion respectively and handles human target image soothingly by using regional filling and morphological filtering on smoothing. Second, the gait feature extraction.

针对提取出的人体目标存在的阴影和空洞，分别采用色彩空间转换的方法对阴影进行检测和消除，采用区域填充和形态学滤波对人体目标图像进行平滑处理。第二，在步态特征提取方面。

Explicit integration schemes for the barotropic primitive equation model are tested for stability and accuracy. Influence of time and space smoothing on the stability and accuracy are also investigated.
