Comments Off on Iterative Vessel Segmentation of Fundus Images
Posted in: IEEE 2017, MATLAB
Iterative Vessel Segmentation of Fundus Images Abstract This paper presents a novel unsupervised iterative blood vessel segmentation algorithm using fundus images. First, a vessel enhanced image is generated by tophat reconstruction of the negative green plane image. An initial estimate of the segmented vasculature is extracted by global thresholding the vessel enhanced image. Next, new […]

Comments Off on Detection and Rectification of Distorted Fingerprints
Posted in: IEEE 2017, MATLAB
Detection and Rectification of Distorted Fingerprints Abstract Elastic distortion of fingerprints is one of the major causes for false non-match. While this problem affects all fingerprint recognition applications, it is especially dangerous in negative recognition applications, such as watchlist and deduplication applications. In such applications, malicious users may purposely distort their fingerprints to evade identification. […]
