Frame detection using gradients fuzzy logic and morphological processing for distant color eye images in an intelligent iris recognition system
Bespectacled eye image will reduce the iris segmentation accuracy. HSV color space provided better space for the segmentation process. Sobel operator and high pass filter provide gradient information on the frame edges. Fuzzy logic is performed as the decision making for frame detection. Dilation operation fills the discontinuity edges of the frame.
