WebWe compare the classical and outstanding Daugman iris location approach with two window based detectors: 1) a sliding window detector based on features from Histogram of Oriented Gradients (HOG) and a linear Support Vector Machines (SVM) classifier; 2) a deep learning based detector fine-tuned from YOLO object detector. Experimental results ... WebDaugman proposed to detect the inner and outer iris boundaries using an active contour method, based on the discrete Fourier series expan- sion of the contour data [1]. Shah and Ross combined snake segmentation with geometric active contours [20].
