ABSTRACT:
A digital radiologic image, notably a mammogram, is automatically processed by a computer to identify suspect masses. The identification is done by thresholding at least a region of interest of the image at, at least, 20 threshold levels determined from a histogram of the image to discriminate spots, and classifying the spots by size, shape and variance in intensity of the pixels comprising the spot. A processed mammogram having the suspect masses marked or enhanced is produced and displayed.
