VSANet: View-aware Sparse Attention Network for Light Field Image Denoising
Gargi Panda, Soumitra Kundu, Saumik Bhattacharya +1
Light field (LF) image denoising is challenging due to the high-dimensional structure of LF data. While noise is independent across sub-aperture images, scene content exhibits stro…
l0-Regularized Sparse Coding-based Interpretable Network for Multi-Modal Image Fusion
Gargi Panda, Soumitra Kundu, Saumik Bhattacharya +1
Multi-modal image fusion (MMIF) enhances the information content of the fused image by combining the unique as well as common features obtained from different modality sensor image…
Hyperspectral Unmixing with 3D Convolutional Sparse Coding and Projected Simplex Volume Maximization
Gargi Panda, Soumitra Kundu, Saumik Bhattacharya +1
Hyperspectral unmixing (HSU) aims to separate each pixel into its constituent endmembers and estimate their corresponding abundance fractions. This work presents an algorithm-unrol…
LifWavNet: Lifting Wavelet-based Network for Non-contact ECG Reconstruction from Radar
Soumitra Kundu, Gargi Panda, Saumik Bhattacharya +2
Non-contact electrocardiogram (ECG) reconstruction from radar signals offers a promising approach for unobtrusive cardiac monitoring. We present LifWavNet, a lifting wavelet networ…
SINET: Sparsity-driven Interpretable Neural Network for Underwater Image Enhancement
Gargi Panda, Soumitra Kundu, Saumik Bhattacharya +1
Improving the quality of underwater images is essential for advancing marine research and technology. This work introduces a sparsity-driven interpretable neural network (SINET) fo…
SSNet: Saliency Prior and State Space Model-based Network for Salient Object Detection in RGB-D Images
Gargi Panda, Soumitra Kundu, Saumik Bhattacharya +1
Salient object detection (SOD) in RGB-D images is an essential task in computer vision, enabling applications in scene understanding, robotics, and augmented reality. However, exis…
