Is Sharing of Egocentric Video Giving Away Your Biometric Signature?

no code implementations ECCV 2020 Daksh Thapar, Chetan Arora, Aditya Nigam

In this work, we create a novel kind of privacy attack by extracting the wearer’s gait profile, a well known biometric signature, from such optical flow in the egocentric videos.

Merry Go Round: Rotate a Frame and Fool a DNN

no code implementations CVPR 2022 Daksh Thapar, Aditya Nigam, Chetan Arora

On the other hand DNNs are known to be susceptible to Adversarial Attacks (AAs) which add im-perceptible noise to the input.

Anonymizing Egocentric Videos

no code implementations ICCV 2021 Daksh Thapar, Aditya Nigam, Chetan Arora

In a more damaging scenario, one can even recognize a wearer using hand gestures from egocentric videos, or identify a wearer in third person videos such as from a surveillance camera.

FKIMNet: A Finger Dorsal Image Matching Network Comparing Component (Major, Minor and Nail) Matching with Holistic (Finger Dorsal) Matching

no code implementations2 Apr 2019 Daksh Thapar, Gaurav Jaswal, Aditya Nigam

In distinguished experiments, the individual performance of finger, as well as weighted sum score level fusion of major knuckle, minor knuckle, and nail modalities have been computed, justifying our assumption to consider full finger as biometrics instead of its counterparts.

PVSNet: Palm Vein Authentication Siamese Network Trained using Triplet Loss and Adaptive Hard Mining by Learning Enforced Domain Specific Features

no code implementations15 Dec 2018 Daksh Thapar, Gaurav Jaswal, Aditya Nigam, Vivek Kanhangad

Designing an end-to-end deep learning network to match the biometric features with limited training samples is an extremely challenging task.

BrainSegNet : A Segmentation Network for Human Brain Fiber Tractography Data into Anatomically Meaningful Clusters

no code implementations14 Oct 2017 Tushar Gupta, Shreyas Malakarjun Patil, Mukkaram Tailor, Daksh Thapar, Aditya Nigam

The segregation of brain fiber tractography data into distinct and anatomically meaningful clusters can help to comprehend the complex brain structure and early investigation and management of various neural disorders.

UBSegNet: Unified Biometric Region of Interest Segmentation Network

no code implementations26 Sep 2017 Ranjeet Ranjan Jha, Daksh Thapar, Shreyas Malakarjun Patil, Aditya Nigam

In this paper, we have proposed a novel end-to-end, Unified Biometric ROI Segmentation Network (UBSegNet), for extracting region of interest from five different biometric traits viz.
