A method for echocardiogram boundary enhancement using local image characteristics and Ratio-of-Averages (RoA) is proposed in this paper. Local image characteristics, namely “steepness” and “symmetry”, are used along side with RoA to determine “edgeness” of the image. The task is achieved by employing a fuzzy inference system where fuzzy sets and rules are derived heuristically to define “edgeness”. All results obtained are compared to a standard edge detector and a similar method without RoA for quantitative and qualitative performance evaluation.
