Automatic Extraction of ROI in Medical Image
医学图像感兴趣区域的自动提取*

A pretreatment algorithm of automatic extraction of ROI(Region Of Interested) is presented,which aims at daily data generated from Picture Archiving and Communication System(PACS), especially those video-captured and film-scanned images. It can be no harm to the ROI data, less time-consuming and no manual-intervened, which befits the batch pretreatment of magnanimity images database. The experiment prove that this algorithm can effect in raising the performance of the subsequent program in content-based images query.
