Interactive Class-Agnostic Object Counting

no code implementations ICCV 2023 Yifeng Huang, Viresh Ranjan, Minh Hoai

The user can provide feedback by selecting a region with obvious counting errors and specifying the range for the estimated number of objects within it.

Object Object Counting

Zero-shot Object Counting

1 code implementation CVPR 2023 Jingyi Xu, Hieu Le, Vu Nguyen, Viresh Ranjan, Dimitris Samaras

By applying this model to all the candidate patches, we can select the most suitable patches as exemplars for counting.

Exemplar Free Class Agnostic Counting

no code implementations27 May 2022 Viresh Ranjan, Minh Hoai

We tackle the task of Class Agnostic Counting, which aims to count objects in a novel object category at test time without any access to labeled training data for that category.

Vicinal Counting Networks

no code implementations29 Sep 2021 Viresh Ranjan, Minh Hoai

Given an image containing multiple objects of a novel visual category and few exemplar bounding boxes depicting the visual category of interest, we want to count all of the instances of the desired visual category in the image.

Crowd Counting Data Augmentation

Learning To Count Everything

1 code implementation CVPR 2021 Viresh Ranjan, Udbhav Sharma, Thu Nguyen, Minh Hoai

We also present a novel adaptation strategy to adapt our network to any novel visual category at test time, using only a few exemplar objects from the novel category.

Uncertainty Estimation and Sample Selection for Crowd Counting

1 code implementation30 Sep 2020 Viresh Ranjan, Boyu Wang, Mubarak Shah, Minh Hoai

We present sample selection strategies which make use of the density and uncertainty of predictions from the networks trained on one domain to select the informative images from a target domain of interest to acquire human annotation.

A Study of Human Gaze Behavior During Visual Crowd Counting

no code implementations14 Sep 2020 Raji Annadi, Yupei Chen, Viresh Ranjan, Dimitris Samaras, Gregory Zelinsky, Minh Hoai

Analyzing the collected gaze behavior of ten human participants on thirty crowd images, we observe some common approaches for visual counting.

Crowd Counting

Crowd Transformer Network

no code implementations4 Apr 2019 Viresh Ranjan, Mubarak Shah, Minh Hoai Nguyen

Most of the existing crowd counting approaches rely on local features for estimating the crowd density map.

Fake Sentence Detection as a Training Task for Sentence Encoding

no code implementations ICLR 2019 Viresh Ranjan, Heeyoung Kwon, Niranjan Balasubramanian, Minh Hoai

We automatically generate fake sentences by corrupting original sentences from a source collection and train the encoders to produce representations that are effective at detecting fake sentences.

Stochastic Multiple Choice Learning for Training Diverse Deep Ensembles

no code implementations NeurIPS 2016 Stefan Lee, Senthil Purushwalkam, Michael Cogswell, Viresh Ranjan, David Crandall, Dhruv Batra

Many practical perception systems exist within larger processes that include interactions with users or additional components capable of evaluating the quality of predicted solutions.

Multi-Label Cross-Modal Retrieval

1 code implementation ICCV 2015 Viresh Ranjan, Nikhil Rasiwasia, C. V. Jawahar

In this work, we address the problem of cross-modal retrieval in presence of multi-label annotations.
