Automatic shot boundary detection is a field, where many techniques and methods have been proposed and have claimed to perform reliably, especially for abrupt scene cut detection. However, all the proposed methods share a common drawback: the necessity of a threshold value, which is used as a reference for detecting scene changes. The determination of the appropriate value or the dynamic reesti...

Several systems based on bookshelf image analysis have been studied for automating bookshelf inspection in libraries and bookstores. In conventional systems, book boundaries are firstly detected for extracting each individual book by using some popular line detection technique, such as Hough transformation. Their detection accuracies, however, are sometimes insufficient. In this paper, we propo...

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, thi...
