NOMARO: Defending against Adversarial Attacks by NOMA-Inspired Reconstruction Operation

1 code implementation IEEE Sensors Letters 2021 Aryaman Sinha, Soumya P. Dash, N. B. Puhan

In this work, a non-orthogonal multiple access (NOMA)-inspired defense method is proposed to mitigate the effect of adversarial attacks, which pose a major challenge towards deep neural networks (DNNs) in multimedia networks.

Cross-spectral Periocular Recognition: A Survey

no code implementations4 Dec 2018 S. S. Behera, Bappaditya Mandal, N. B. Puhan

Among many biometrics such as face, iris, fingerprint and others, periocular region has the advantages over other biometrics because it is non-intrusive and serves as a balance between iris or eye region (very stringent, small area) and the whole face region (very relaxed large area).

FoodNet: Recognizing Foods Using Ensemble of Deep Networks

no code implementations27 Sep 2017 Paritosh Pandey, Akella Deepthi, Bappaditya Mandal, N. B. Puhan

In this work we propose a methodology for an automatic food classification system which recognizes the contents of the meal from the images of the food.
