forms and stores the corresponding orientation histograms. In the run phase, the computer compares the orientation histogram of the current image with each of the stored templates and selects the category of the closest match, or interpolates between templates, as appropriate. This method should be robust against small differences in the size of the hand but probably would be sensitive to changes in hand orientation. 4. DIGITAL IMAGE PROCESSING
