Evaluation is an important step in developing a segmentation algorithm for an image analysis system. We rst give a review of segmentation evaluation methods, and then demonstrate how a supervisedâ€¦ (More)

When artifical neural networks (ANN) are used in the prediction problems, it is usually desirable that some form of confidence bound is placed on the predicted value. Methods to estimate theâ€¦ (More)

The area and the perimeter of a planar object are two useful features to describe the shape of the object, and again the motion of i t . This paper deals with the estimation of the two features fromâ€¦ (More)

Green's theorem evaluates a double integral over the region of an object by a simple integration along the boundary of the object. It has been used in moment computation since the shape of a binaryâ€¦ (More)

A discrete Gauss' theorem is presented. Using a fast surface tracking algorithm and the discrete Gauss' theorem, we design a new method to compute the Cartesian geometric moments of 3-D objects.â€¦ (More)

A new texture analysis approach is applied to the problem of classiication of pathological states from electron microscopy images of mouse liver cell nuclei. For each pixel in the image, a region ofâ€¦ (More)
