摘要

实现了对视频序列中伪迹的搜索,以发现可能导致纤毛运动误检的物体。视频序列中的运动可以由呼吸上皮的纤毛产生,也可以由一些伪影产生,如红细胞、气泡或呼吸上皮的死细胞。在对运动区域进行评估时,去除导致运动错误检测的伪影是一项重要任务。本文讨论了搜索和去除可能导致错误检测移动区域的伪影的程序和方法。最后在结果部分对四种最典型视频中模式匹配检测伪影的有效性进行了比较和评价。

Artefacts detection for video sequences analysis
The searching for artefacts in video sequences is realized to find objects which can cause false detection of cilia's movement. The motion in video sequence can be generated by cilia of respiratory epithelium as well as by some artefacts, e.g. red blood cells, air bubbles or dead cells of the respiratory epithelium. Removal of artefacts causing false detections of movement is an important task when the motion area is evaluated. This article deals with the procedures and methods which enable searching and removing such artefacts that may cause incorrect detection of moving area. The effectiveness of pattern matching for artefacts detections in four most typical videos is finally compared and evaluated in results paragraph.
