Zero-Shot SAM2 Segmentation and Vision Transformer-Based Recognition of Elamite Cuneiform Symbols from Degraded Tablet Images
Utsav Poudel, Rasik Bhattarai, Siddhartha Pathak +2
Automated recognition of ancient cuneiform script poses a compound signal-degradation problem: the three-dimensional relief of clay tablets creates spatially varying illumination a…
CLRecogEye : Curriculum Learning towards exploiting convolution features for Dynamic Iris Recognition
Geetanjali Sharma, Gaurav Jaswal, Aditya Nigam +1
Iris authentication algorithms have achieved impressive recognition performance, making them highly promising for real-world applications such as border control, citizen identifica…
Generating Realistic Forehead-Creases for User Verification via Conditioned Piecewise Polynomial Curves
Abhishek Tandon, Geetanjali Sharma, Gaurav Jaswal +2
We propose a trait-specific image generation method that models forehead creases geometrically using B-spline and Bézier curves. This approach ensures the realistic generation of b…
Impact of Iris Pigmentation on Performance Bias in Visible Iris Verification Systems: A Comparative Study
Geetanjali Sharma, Abhishek Tandon, Gaurav Jaswal +2
Iris recognition technology plays a critical role in biometric identification systems, but their performance can be affected by variations in iris pigmentation. In this work, we in…
Synthetic Forehead-creases Biometric Generation for Reliable User Verification
Abhishek Tandon, Geetanjali Sharma, Gaurav Jaswal +2
Recent studies have emphasized the potential of forehead-crease patterns as an alternative for face, iris, and periocular recognition, presenting contactless and convenient solutio…
FH-SSTNet: Forehead Creases based User Verification using Spatio-Spatial Temporal Network
Geetanjali Sharma, Gaurav Jaswal, Aditya Nigam +1
Biometric authentication, which utilizes contactless features, such as forehead patterns, has become increasingly important for identity verification and access management. The pro…
