Deep Convolutional Generative Adversarial Network Based Food Recognition Using Partially Labeled Data

no code implementations26 Dec 2018 Bappaditya Mandal, N. B. Puhan, Avijit Verma

Our work aims at developing an efficient deep CNN learning-based method for food recognition alleviating these limitations by using partially labeled training data on generative adversarial networks (GANs).

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).

Deep Adaptive Temporal Pooling for Activity Recognition

no code implementations22 Aug 2018 Sibo Song, Ngai-Man Cheung, Vijay Chandrasekhar, Bappaditya Mandal

Specifically, using frame-level features, DATP regresses importance of different temporal segments and generates weights for them.

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.

Distinguishing Posed and Spontaneous Smiles by Facial Dynamics

no code implementations6 Jan 2017 Bappaditya Mandal, David Lee, Nizar Ouarti

In this work, we propose a cluster of approaches to classify posed and spontaneous smiles using deep convolutional neural network (CNN) face features, local phase quantization (LPQ), dense optical flow and histogram of gradient (HOG).

Spontaneous vs. Posed smiles - can we tell the difference?

no code implementations23 May 2016 Bappaditya Mandal, Nizar Ouarti

Smile is an irrefutable expression that shows the physical state of the mind in both true and deceptive ways.

Improved Eigenfeature Regularization for Face Identification

no code implementations10 Feb 2016 Bappaditya Mandal

In this work, we propose to divide each class (a person) into subclasses using spatial partition trees which helps in better capturing the intra-personal variances arising from the appearances of the same individual.

Face Recognition: Perspectives from the Real-World

no code implementations9 Feb 2016 Bappaditya Mandal

In this paper, we analyze some of our real-world deployment of face recognition (FR) systems for various applications and discuss the gaps between expectations of the user and what the system can deliver.
