1. A method for the automated analysis of a digital image comprising an array of pixels, including the steps of using a computer or processor for:
identifying certain pixels to exclude from the following step, consequent upon a local property of such pixels;
generating a property co-occurrence matrix (PCM) from pixels not identified to be excluded by the preceding step, using the properties of local mean and local standard deviation of intensity in neighbourhoods of the included pixels; and
segmenting the image by labelling the pixels which are included in the formation of said PCM as belonging to specified classes consequent upon analysis of said PCM and by labeling pixels which are excluded from the formation of said PCM as belonging to a specified class different from the first-mentioned classes.
