Liu M, Wang F, Wang X, Wang Y, Roy-Chowdhury A
IEEE Trans Pattern Anal Mach Intell
. 2024 Feb;
46(7):4944-4956.
PMID: 38306260
Supervised person re-identification (Re-ID) approaches are sensitive to label corrupted data, which is inevitable and generally ignored in the field of person Re-ID. In this paper, we propose a two-stage...

Nag S, Raychaudhuri D, Paul S, Roy-Chowdhury A
IEEE Trans Pattern Anal Mach Intell
. 2023 Sep;
45(12):15394-15405.
PMID: 37773900
In many applications, we are constrained to learn classifiers from very limited data (few-shot classification). The task becomes even more challenging if it is also required to identify samples from...

Paul S, Mithun N, Roy-Chowdhury A
IEEE Trans Image Process
. 2021 Oct;
30:8886-8899.
PMID: 34665727
Prior works on text-based video moment localization focus on temporally grounding the textual query in an untrimmed video. These works assume that the relevant video is already known and attempt...

Wang X, Liu M, Raychaudhuri D, Paul S, Wang Y, Roy-Chowdhury A
IEEE Trans Image Process
. 2021 Feb;
30:3017-3028.
PMID: 33571092
Most person re-identification methods, being supervised techniques, suffer from the burden of massive annotation requirement. Unsupervised methods overcome this need for labeled data, but perform poorly compared to the supervised...

Bappy J, Paul S, Tuncel E, Roy-Chowdhury A
IEEE Trans Image Process
. 2019 Apr;
PMID: 30998468
In this paper, we present a novel approach to find informative and anomalous samples in videos exploiting the concept of typicality from information theory. In most video analysis tasks, selection...

Bappy J, Simons C, Nataraj L, Manjunath B, Roy-Chowdhury A
IEEE Trans Image Process
. 2019 Feb;
28(7):3286-3300.
PMID: 30703026
With advanced image journaling tools, one can easily alter the semantic meaning of an image by exploiting certain manipulation techniques such as copy clone, object splicing, and removal, which mislead...

Hasan M, Paul S, Mourikis A, Roy-Chowdhury A
IEEE Trans Pattern Anal Mach Intell
. 2018 Nov;
42(3):554-567.
PMID: 30387722
Activity recognition is a challenging problem with many practical applications. In addition to the visual features, recent approaches have benefited from the use of context, e.g., inter-relationships among the activities...

Panda R, Mithun N, Roy-Chowdhury A
IEEE Trans Image Process
. 2017 Jun;
26(10):4712-4724.
PMID: 28574359
Most video summarization approaches have focused on extracting a summary from a single video; we propose an unsupervised framework for summarizing a collection of videos. We observe that each video...

Mkrtchyan K, Chakraborty A, Roy-Chowdhury A
IEEE/ACM Trans Comput Biol Bioinform
. 2016 Feb;
14(2):457-467.
PMID: 26887008
Technologically advanced imaging techniques have allowed us to generate and study the internal part of a tissue over time by capturing serial optical images that contain spatio-temporal slices of hundreds...

Chakraborty A, Das A, Roy-Chowdhury A
IEEE Trans Pattern Anal Mach Intell
. 2015 Oct;
38(9):1859-71.
PMID: 26485472
Existing data association techniques mostly focus on matching pairs of data-point sets and then repeating this process along space-time to achieve long term correspondences. However, in many problems such as...
