So the video segmentation research in this paper is based on mpeg video . shot detection is the most fundamental operation and very important step in cbvar . shot detection is a technique that divides video data into physical units , generally called shots 在解壓域的鏡頭檢測(cè)中,提出一種基于視覺(jué)特征的突變鏡頭檢測(cè)方法;在壓縮域的鏡頭檢測(cè)中,本文采用了基于宏塊類型信息的鏡頭檢測(cè)方法,可以有效的檢測(cè)出突變和部分漸變鏡頭。
Through analyzing segmentation methods in existence , this paper points out three developing directions of future chinese automatic segmentation research , that is , effective segmentation to traditional text , rapid development of computer technology , and changing the writing rules of chinese text 本文通過(guò)對(duì)現(xiàn)有分詞方法的分析,指出了今后漢語(yǔ)自動(dòng)分詞研究的三個(gè)發(fā)展方向,即對(duì)傳統(tǒng)文本的有效切分,計(jì)算機(jī)技術(shù)的快速發(fā)展,改造書(shū)面漢語(yǔ)書(shū)寫(xiě)規(guī)則。
