Abstract
We present an algorithm that uses the zero-crossing information obtained from multiple resolution Laplacian of a 2-D Gaussian (VG) filtering to estimate the location, orientation, width (blur) and shape of the intensity changes in an image. Based on a ramp edge model of image edges, the algorithm uses the response zero-crossing slope to determine the width of a possible intensity change. It describes the intensity change in the region about the zero-crossing from the derivatives of the Gaussian smoothed image at the filter scale corresponding to the width.
