Abstract

Two smoothed images, each processed with a different smoothing factor, can be subtracted providing the information difference between the least smoothed and the most smoothed data set. The smoothing technique of this invention comprises a two-dimensional digital hysteresis filter utilizing a "two-dimensional automatically adjusting variable mask". As a result, the filter is independent of the image size and content and cannot alter the size of any significant intensity features. The two-dimensional hysteresis smoothing technique of this invention calculates the intensity value of smoothed pixels using a set of one-dimensional hysteresis lines at various angles running through each pixel in an image. These one-dimensional hysteresis values are added together and divided by the number of hysteresis lines to get the output value for the pixel. The intensity processing technique provides the basis for a separation of the image information into basic information groups.
