Multigradient field-active contour model for multilayer boundary detection of ultrasound rectal wall image
Journal of Electronic Imaging (JEI)
Extraction and reconstruction of rectal wall structures from an ultrasound image is helpful for surgeons in rectal clinical diagnosis and 3-D reconstruction of rectal structures from ultrasound images. The primary task is to extract the boundary of the muscular layers on the rectal wall. However, due to the low SNR from ultrasound imaging and the thin muscular layer structure of the rectum, this boundary detection task remains a challenge. An active contour model is an effective high-leveldoi:10.1117/1.1992500 fatcat:rme5kcdodrh5fimdpqy7ccq5gi
