Vein Pattern Recognition Using ROI Extraction

Abstract

This paper presents a new approach to vein pattern recognition system. The various stages involved are Image acquisition, Region Of Interest Extraction. Our main focus is on Dynamic ROI Extraction and thinning. We got a database of hand images which are far infrared images of hand. For that images, we have done dynamic ROI extraction. The advantage of dynamic ROI extraction is that ROI extracted for different hand images varies in size as the size of the hand varies. As the size of ROI varies, we can extract more features from larger hand. We’ve proposed a new thinning algorithm which involves thinning the ROI to one pixel thick medial axis vein network and also removal of thinning artifacts. We used a sequential
