In this study, a modified topology-adaptive snake (T-snake) is proposed for the segmentation of ultrasound image. The algorithm was improved as follows. First, the image is decomposed in the place which has offset from pixel's position while snake points are in pixel's position. This will reduce the task during calculating intersections between contour and ACID grid. Second, the rule to process topology...
Low signal noise ratio (SNR) of the ultrasound images makes the segmentation of fetal lung a difficult task. In this paper, a novel method using the texture-based boundary enhancement and active contour models is developed to semi-automatically segment the fetal lung from fetal chest ultrasound images. The texture-based boundary enhancement procedure is firstly proposed to enhance boundary regions...
