Abstract :
An approach to the automatic boundary detection on gastrointestinal-wall ultrasound images (GWUI) is investigated. Boundaries are found by using the following major processing steps: asymmetrical two-dimensional median filtering; asymmetrical two-dimensional neighborhood averaging; global thresholding; binary image transformation; and local edge detection. Preliminary results from outlining layers within eight different GWUIs are presented
