Linear feature enhancement by false color

Abstract

This paper presents a technique of enhancing linear features in ultrasonic imagery by use of a false color. Color is used to indicate the direction of the most prominent line segment at each point, as determined by a detection algorithm. The resulting enhanced images contain additional information which is not directly available in the unprocessed image. Because the direction and original gray scale intensity are presented in orthogonal color components-hue and intensity, respectively, in (H, S, I) color space-the color information can be quickly removed to restore the original image for conventional diagnosis.
