摘要
近些年,视频分割与检索吸引了越来越多人的注意。在视频检索系统中,镜头边缘检测至关重要。在分块颜色直方图和颜色亮度特征基础上提出一种新的突变镜头分割法。一种自适应门限机制和软性联合判决机制被使用而增强了镜头分割的鲁棒性和有效性。仿真实验主要和其它一些已有的方法进行效果比较,证明了该分割算法的高效性和正确性。
In recent years,video segmentation and retrieval has attracted attentions of more and more people.In video retrieval systems,shot boundary detection is of vital importance.On the basis of block color histogram and color luminance features,a new abrupt change shot segmentation method is proposed.An adaptive threshold mechanism and a soft joint determination mechanism are utilized to enhance the robustness and effectiveness of shot segmentation.By comparing its effect chiefly against a few existing methods,the simulation experiment validates the segmentation algorithm＇s efficiency and correctness.
