Sift vectors
WebThe D-SIFT features (descriptors), extracted from the ROIs, are classified using Support Vector Machines (SVM). The proposed method is tested with the self-created and Caltech databases. Experimental procedures show that the proposed method facilitates recognition with mean accuracy of 85% even in case of partial occlusions.
