The advent and accelerated adoption of laparoscopic surgery requires an objective assessment of both operative performance and perceptual events that lead to clinical decisions. In this paper we present a framework to...
详细信息
Level set methods have been widely employed in medicalimage segmentation, and the construction of speed function is vital to segmentation results. In this paper, two ideas for enriching the speed function in level se...
