Finger Vein Image ROI Extraction Based on Active Contour Method

Abstract: Under the background of the novel coronavirus pneumonia outbreak in the world, unrestricted and contactless finger vein collection devices have significantly improved public health safety. However, due to the unfixed position of the finger and the open or semi-open characteristics of the acquisition device, it is inevitable to introduce plenty of factors that affect the recognition performance, such as low contrast, uneven illumination and edge disappearance. In view of these practical problems, we propose a m… Show more

“…Tao et al [ 13 ] used the Mask RCNN method to predict the ROI mask. Wang et al [ 14 ] used the active contour model (ACM) to obtain the finger vein ROI mask. Gao et al [ 15 ] proposed simplified statistical region merging (SSRM) to obtain finger regions, and a new directed link clustering method (DLCM) and parameter selection (PS) were introduced to ensure edge qualification and further correct the tilt angle.…”
