New DARPA Grant on Adversarial Machine Learning

Amit Roy-Chowdhury is leading a team of ECE and CSE faculty that has received a grant totaling almost $1 million from the Defense Advanced Research Projects Agency, or DARPA, to understand the vulnerability of computer vision systems to adversarial attacks. The project is part of the Techniques for Machine Vision Disruption program, which is part...

Three papers accepted to ACM-Multimedia 2020

Papers on High-Frame Rate Video Enhancement, Adversarial Knowledge Transfer and Video Fast-Forwarding accepted to ACM-MM 2020. The paper, ALANET: Adaptive Latent Attention Network for Joint Video Deblurring and Interpolation, accepted as oral in ACM-MM 2020, proposes the Adaptive Latent Attention Network (ALANET), to synthesize sharp high frame-rate videos by jointly performing the task of both...

Three papers accepted to ECCV 2020

Three papers on different topics were accepted to ECCV 2020 The paper titled "Domain Adaptive Semantic Segmentation Using Weak Labels" proposes a unified framework for both unsupervised domain adaptation when using the estimated pseudo-weak labels and the novel scenario of weakly-supervised adaptation when using weak labels acquired from human annotators. This work bridges the gap...

Two papers accepted to CVPR 2020

Papers on Non-Adversarial Video Synthesis with Learned Priors and Camera On-boarding for Person Re-identification using Hypothesis Transfer Learning are accepted to CVPR 2020. 1. The paper, Non-Adversarial Video Synthesis with Learned Priors, in CVPR 2020 proposes an approach to generate videos from latent noise vectors, without any reference input frames by jointly optimizing the input...

Paper on Subgoal Discovery accepted in NeurIPS 2019

Our recent paper, Learning from Trajectories via Subgoal Discovery, in NeurIPS 2019 proposes an approach to discover subgoals to solve complex tasks, from a limited number of expert demonstrations. Using these discovered subgoals leads to significantly faster robotic task learning with none to limited hand-designing of rewards. This work is done in collaboration between UCR...

NSF Grant “III: Medium: Efficient Collaborative Perception over Controllable Agent Networks”

New 1.2 Million NSF grant “III: Medium: Efficient Collaborative Perception over Controllable Agent Networks” was awarded to a team of 3 CSE Professors: Vagelis Christidis (PI), Vassilis Tsotras, and Vagelis Papalexakis and 2 ECE Professors: Amit Roy-Chowdhury and Konstantinos Karydis.

New grant to make artificial intelligent (AI) systems smarter

Amit Roy-Chowdhury, Konstantinos Karydis, and Salman Asif, electrical and computer engineering professors, along with Fabio Pasqualetti, a mechanical engineering professor, receive a $1.2M grant from the Office of Naval Research’s Science of Artificial Intelligence Program. Using recent advances in computer vision, machine learning, signal processing, robotics, and controls, researchers will explore AI’s capability of both...

Multiple papers on learning with limited supervision

VCG researchers have recently published a number of papers of learning in computer vision with limited supervision.

Joint Image/Video and Text Analysis

Recent papers in CVPR, ACM MM, and ACM ICMR have analyzed the issue of jointly analyzing visual and textual data. The CVPR-19 paper focuses on video moment retrieval based on associated captions, the ACM MM-18 paper considers web supervision for retrieval in joint image-text databases with limited labeled data, while the ICMR paper considered cross-modal...

Protecting Against Image/Video Manipualtions

A recent paper in T-IP proposed a novel deep network architecture for identifying image forgeries and presented results on multiple state-of-the-art datasets. A paper in NDSS-19 proposed how an adversary could design perturbations in video classification systems. Hybrid LSTM and Encoder-Decoder Architecture for Detection of Image Forgeries, IEEE Trans. on Image Processing, 2019. Adversarial Perturbations...
