%X We present a method for automatic detection of left ventricle (LV) contour in gated blood pool studies based on G operator, used as an enhancing filter. The LV is localized automatically in the diastolic frame using a fuzzy membership function of localization over the filtered image. After that, the LV contour is searched by a region growing algorithm with constraints in the diastolic frame. In the other frames, contours are detected via heuristic local search using the previously detected contour as a template and looking for an optimal path.
