A hybrid segmentation scheme for improved dorsal hand vein recognition

The dorsal hand vein (DHV) pattern is a highly secured biometric system that is significantly used in many applications due to its uniqueness. Although it is a safe and secure means for biometric identification, accurate recognition of vein patterns for this application remains challenging. To solve...

A hybrid segmentation scheme for improved dorsal hand vein recognition
description The dorsal hand vein (DHV) pattern is a highly secured biometric system that is significantly used in many applications due to its uniqueness. Although it is a safe and secure means for biometric identification, accurate recognition of vein patterns for this application remains challenging. To solve the issue, various machine learning (ML) and deep learning (DL) techniques were employed in the past to identify DHV correctly. A hybrid ML and DL strategy are adopted in this study. An automatic segmentation technique designed based on the histogram, thresholding and morphological operations is proposed to overcome the shortcomings of manual segmentation. The Bosphorus database is used for demonstration. While the first set of the experiment used the original segmented dataset, the second combines the original dataset with the augmented images generated using the combinations of rotation transformations (i.e., [30˚ -30˚] and [50˚ -50˚]) and flipping.
