视频图象中的目标系列分割法

把视频图像或时间系列图象中的某一景物持续一段时间后才变化为另一景物称为一个目标系列。对目标系列进行分割是应用多媒体技术在计算机上处理视频图象成时间系列图象的基础。本文研究了目标系列分割的各种方法，先建立了分割的特征空间，然后根据特征空间的直方图提出了阈值分割法和变换阈值分割法，在详细研究这些分割方法特点的基础上，指出了在不同情况下如何选择合适的分割调整参数以获得最佳的分割效果。

Succeeding Objectives Cut Method for Video Image

Succeeding objectives in video is defined as the change from a scenery to another in thelasting time. The cut for objective is base of video image processing under multimedia technique.Various cut methods are discussed in this paper. First the characteristic space is built. Then thehistogram threshold cut method and the histogram transform cut method are studied in detailfilm-video conversion, animation, slow motion pictures, and flash in objective image. Finallyhow to select suitable regulating parameters of the histogram transform cut method to obtain optimal cut is studied.
