In many object recognition systems only geometric constraints on the boundaries of the objects are used. Many authors have shown the merit in determining the distinctiveness of boundary constraints, and using these to speed up and improve the robustness of object recognition algorithms. However, if the objects have variable shapes or the image is cluttered,(More)
The aim of this work is to find out whether the grey level symmetric axis transform (SAT) is a useful grey level shape description for finding the salient cavities in echocardiograms. The centres of the maximal discs of the grey level SAT are calculated using mathematical morphology as described by Peleg and Rosenfeld, and these centres are grouped to form(More)
