abrupt transition meaning in Chinese

挤塑模头陡变区

In video shot segmentation , an improvement to double - threold shot segmentation algorithm is provided , which uses multi - frame sampling technique and can improve the performance significantly on the detection of gradual transition . an abrupt transition detection algorithm is also developed on the basis of the closest pixels matching in spatio - temporal slice , which decreases the false rate and computing strength greatly
在视频镜头分割方面,提出了一种基于多帧抽样的双重比较镜头分割算法,有效地提高了对视频镜头渐变检测的性能;同时,针对视频镜头突变的检测,提出了一种基于最近邻像素匹配的时空切片镜头突变检测算法,该算法显著降低了突变检测的虚检率和计算量。
