Multiplicative noise is one of the most aggressive types of noise present in various types of
images: Synthetic Aperture Radar, Ultrasound images, Ultrasonic Imaging, among others …

In this paper, a new operator for contour detection in images with multiplicative noise is
presented. Traditional methods of edge detection, as those based in gradient operator or …

Intravascular ultrasound (IVUS)-based tissue characterization is invaluable for the computer-
