Abstract : Nonlinear scalespace should be based on a hierarchical statistical model of the image intensity function. This model should contain an explicit representation of the multiscale structure of edges and corners. Using this model we can have a nonadhoc basis for computing the parameters we need to determine how much smoothing we should do at points that appear to be edge points. We also have a basis for computing the apparent error in our scalespace calculations. Hierarchical statistical modeling is a technique that can be applied to other problems in lowlevel vision, but in this introductory paper we just present the application of our scalespace theory to image smoothing.
