CCPA: Long-term Person Re-Identification via Contrastive Clothing and Pose Augmentation

no code implementations22 Feb 2024 Vuong D. Nguyen, Shishir K. Shah

Long-term Person Re-Identification (LRe-ID) aims at matching an individual across cameras after a long period of time, presenting variations in clothing, pose, and viewpoint.

Data Quality Aware Approaches for Addressing Model Drift of Semantic Segmentation Models

no code implementations11 Feb 2024 Samiha Mirza, Vuong D. Nguyen, Pranav Mantini, Shishir K. Shah

In the midst of the rapid integration of artificial intelligence (AI) into real world applications, one pressing challenge we confront is the phenomenon of model drift, wherein the performance of AI models gradually degrades over time, compromising their effectiveness in real-world, dynamic environments.

Attention-based Shape and Gait Representations Learning for Video-based Cloth-Changing Person Re-Identification

no code implementations6 Feb 2024 Vuong D. Nguyen, Samiha Mirza, Pranav Mantini, Shishir K. Shah

Our ASGL framework improves Re-ID performance under clothing variations by learning clothing-invariant gait cues using a Spatial-Temporal Graph Attention Network (ST-GAT).

SHaPE: A Novel Graph Theoretic Algorithm for Making Consensus-Based Decisions in Person Re-Identification Systems

no code implementations ICCV 2017 Arko Barman, Shishir K. Shah

In this paper, we formulate an algorithm that maps the ranking process in a person re-identification algorithm to a problem in graph theory.

End-to-end 3D face reconstruction with deep neural networks

no code implementations CVPR 2017 Pengfei Dou, Shishir K. Shah, Ioannis A. Kakadiaris

Inspired by the success of deep neural networks (DNN), we propose a DNN-based approach for End-to-End 3D FAce Reconstruction (UH-E2FAR) from a single 2D image.
