Object-Aware Cropping for Self-Supervised Learning

1 code implementation1 Dec 2021 Shlok Mishra, Anshul Shah, Ankan Bansal, Abhyuday Jagannatha, Janit Anjaria, Abhishek Sharma, David Jacobs, Dilip Krishnan

This assumption is mostly satisfied in datasets such as ImageNet where there is a large, centered object, which is highly likely to be present in random crops of the full image.

Learning Visual Representations for Transfer Learning by Suppressing Texture

1 code implementation3 Nov 2020 Shlok Mishra, Anshul Shah, Ankan Bansal, Janit Anjaria, Jonghyun Choi, Abhinav Shrivastava, Abhishek Sharma, David Jacobs

Recent literature has shown that features obtained from supervised training of CNNs may over-emphasize texture rather than encoding high-level information.

Pose And Joint-Aware Action Recognition

1 code implementation16 Oct 2020 Anshul Shah, Shlok Mishra, Ankan Bansal, Jun-Cheng Chen, Rama Chellappa, Abhinav Shrivastava

Unlike other modalities, constellation of joints and their motion generate models with succinct human motion information for activity recognition.

Spatial Priming for Detecting Human-Object Interactions

no code implementations9 Apr 2020 Ankan Bansal, Sai Saketh Rambhatla, Abhinav Shrivastava, Rama Chellappa

The proposed method consists of a layout module which primes a visual module to predict the type of interaction between a human and an object.

How are attributes expressed in face DCNNs?

no code implementations12 Oct 2019 Prithviraj Dhar, Ankan Bansal, Carlos D. Castillo, Joshua Gleason, P. Jonathon Phillips, Rama Chellappa

In the final fully connected layer of the networks, we found the order of expressivity for facial attributes to be Age > Sex > Yaw.

Detecting Human-Object Interactions via Functional Generalization

no code implementations5 Apr 2019 Ankan Bansal, Sai Saketh Rambhatla, Abhinav Shrivastava, Rama Chellappa

We present an approach for detecting human-object interactions (HOIs) in images, based on the idea that humans interact with functionally similar objects in a similar manner.

Zero-Shot Object Detection

no code implementations ECCV 2018 Ankan Bansal, Karan Sikka, Gaurav Sharma, Rama Chellappa, Ajay Divakaran

We introduce and tackle the problem of zero-shot object detection (ZSD), which aims to detect object classes which are not observed during training.

Crystal Loss and Quality Pooling for Unconstrained Face Verification and Recognition

no code implementations3 Apr 2018 Rajeev Ranjan, Ankan Bansal, Hongyu Xu, Swami Sankaranarayanan, Jun-Cheng Chen, Carlos D. Castillo, Rama Chellappa

We show that integrating this simple step in the training pipeline significantly improves the performance of face verification and recognition systems.

UPSET and ANGRI : Breaking High Performance Image Classifiers

no code implementations4 Jul 2017 Sayantan Sarkar, Ankan Bansal, Upal Mahbub, Rama Chellappa

In this paper, targeted fooling of high performance image classifiers is achieved by developing two novel attack methods.

The Do's and Don'ts for CNN-based Face Verification

no code implementations21 May 2017 Ankan Bansal, Carlos Castillo, Rajeev Ranjan, Rama Chellappa

While the research community appears to have developed a consensus on the methods of acquiring annotated data, design and training of CNNs, many questions still remain to be answered.

UMDFaces: An Annotated Face Dataset for Training Deep Networks

no code implementations4 Nov 2016 Ankan Bansal, Anirudh Nanduri, Carlos Castillo, Rajeev Ranjan, Rama Chellappa

Recent progress in face detection (including keypoint detection), and recognition is mainly being driven by (i) deeper convolutional neural network architectures, and (ii) larger datasets.
