Examples of the three phenotypes and their corresponding image descriptors.
(a). Local Edge Histogram for each of 4×4 image blocks (y axis of each of the 4×4 image blocks is from 0 to 6. (b). Representative Color (i.e., the average color (grayscale) for each of the 4×4 image blocks). (c). Color Histogram (x axis is the graryscale that ranges from 0 to 255; y axis is from 0 to 16×104 identifying the number of pixels which grayscale are within the bin range).
