Source-Free Online Domain Adaptive Semantic Segmentation of Satellite Images under Image Degradation

no code implementations4 Jan 2024 Fahim Faisal Niloy, Kishor Kumar Bhaumik, Simon S. Woo

In this paper, we address source-free and online domain adaptation, i. e., test-time adaptation (TTA), for satellite images, with the focus on mitigating distribution shifts caused by various forms of image degradation.

STLGRU: Spatio-Temporal Lightweight Graph GRU for Traffic Flow Prediction

1 code implementation8 Dec 2022 Kishor Kumar Bhaumik, Fahim Faisal Niloy, Saif Mahmud, Simon Woo

Specifically, our proposed STLGRU can effectively capture dynamic local and global spatial-temporal relations of traffic networks using memory-augmented attention and gating mechanisms in a continuously synchronized manner.

CFL-Net: Image Forgery Localization Using Contrastive Learning

no code implementations4 Oct 2022 Fahim Faisal Niloy, Kishor Kumar Bhaumik, Simon S. Woo

A key assumption in underlying forged region localization is that there remains a difference of feature distribution between untampered and manipulated regions in each forged image sample, irrespective of the forgery type.

Variational Stacked Local Attention Networks for Diverse Video Captioning

no code implementations4 Jan 2022 Tonmoay Deb, Akib Sadmanee, Kishor Kumar Bhaumik, Amin Ahsan Ali, M Ashraful Amin, A K M Mahbubur Rahman

However, growing model complexity for visual data encourages more explicit feature interaction for fine-grained information, which is currently absent in the video captioning domain.

Human Activity Recognition from Wearable Sensor Data Using Self-Attention

2 code implementations17 Mar 2020 Saif Mahmud, M Tanjid Hasan Tonmoy, Kishor Kumar Bhaumik, A K M Mahbubur Rahman, M Ashraful Amin, Mohammad Shoyaib, Muhammad Asif Hossain Khan, Amin Ahsan Ali

In this regard, the existing recurrent or convolutional or their hybrid models for activity recognition struggle to capture spatio-temporal context from the feature space of sensor reading sequence.
