Abstract :
A multiscale region detector for low-level image analysis is described. The basis of the detector is a set of filters similar to the Laplacian of an elliptical Gaussian. The responses of these filters to ideal ellipses are derived, and equations for determining the parameters of detected ellipses from the filter responses are found. The use of scale-space techniques to eliminate false ellipse sites in real images is described
