In addition, other key problems such as video temporal segmentation, color space selection and temporal filtering are discussed and an adaptive threshold video shot cut detection algorithm and a weighted median-filtering algorithm are presented as solution.

此外，本文还对视频时域分割、颜色空间选取、空域滤波等时空域分割要解决关键问题进行了探讨，并提出了一种自适应阈值切变镜头探测算法和加权中值滤波算法来解决这些问题。

Filtering is a basic operation in image processing and computer vision. Gaussian low-pass filtering is the most commonly used, and its principle is weighted average of neighborhood pixels value.

滤波是图像处理和计算机视觉中最基本的操作，高斯低通滤波是最常用的，其原理是邻域内像素值的加权平均。

A nonlinear tensor-valued weighted directional-distance filtering method is proposed for regularizing the diffusion tensor field produced by diffusion tensor magnetic resonance imaging.
