Histograms of PHOG Descriptors for Benign and Malignant Tumours in US Images. The histograms of PHOG descriptors that extracted local shape and the spatial layout from images and quantified them as vectors for (a) a probably benign US image (Fig. 2a, level = 2, bin = 30, total 630 features) and (b) a moderate suspicion for malignancy US image (Fig. 3a, level = 2, bin = 30, total 630 features).
