Paper Abstract

Ultrasonic images of the heart, i.e. echocardiographs, have been in use in diagnosis and treatment for some time, the quality of the images is not good. This paper describes a procedure for enhancing and improving the quality of echocardiographs. The procedure described has three main aspects: noise filtering or smoothing, edge extraction and contour following. A number of filtering algorithms to eliminate noise and smooth the image are presented and their advantages reviewed. Several edge operators are considered and their merits discussed, and a modification to one is presented. Contour tracing algorithms are studied and a modification proposed. The resulting procedure is illustrated in each step.
