Estimating Motion in Ultrasound Images of the Small Bowel: Optical Flow without Image Structure

Abstract

Measurement of motion in transabdominal ultrasound sequences of the small bowel is hampered by the unstructured, textured appearance of the images. We investigate a method of measuring Optical Flow in the sequences, based on an analysis of the spatio-temporal frequency spectrum. The method requires no unrealistic assumptions about the distribution of energy… (More)
