Decide what kind of fruit it is by lowest score. using Matlab

step1: make a standardized template library (all fruit, 51x51). step2: extract an individual object from an image and generate a single line edge (contour). step3: standardize the image (normalized, single line, 51x51). step4: use the central point as fix point, clockwise scan the two template images (contour projection). step5: choose a tolerance value (3 or 5 pixels) to evaluate the image with each template, and get a score (contour matching). step6: decide what kind of fruit it is by lowest score
