Designed Dithering Sign Activation for Binary Neural Networks

1 code implementation3 May 2024 Brayan Monroy, Juan Estupiñan, Tatiana Gelvez-Barrera, Jorge Bacca, Henry Arguello

Binary Neural Networks emerged as a cost-effective and energy-efficient solution for computer vision tasks by binarizing either network weights or activations.

Mixture-Net: Low-Rank Deep Image Prior Inspired by Mixture Models for Spectral Image Recovery

no code implementations5 Nov 2022 Tatiana Gelvez-Barrera, Jorge Bacca, Henry Arguello

This paper proposes a non-data-driven deep neural network for spectral image recovery problems such as denoising, single hyperspectral image super-resolution, and compressive spectral imaging reconstruction.

Deep Coding Patterns Design for Compressive Near-Infrared Spectral Classification

no code implementations27 May 2022 Jorge Bacca, Alejandra Hernandez-Rojas, Henry Arguello

Compressive spectral imaging (CSI) has emerged as an attractive compression and sensing technique, primarily to sense spectral regions where traditional systems result in highly costly such as in the near-infrared spectrum.

D$^\text{2}$UF: Deep Coded Aperture Design and Unrolling Algorithm for Compressive Spectral Image Fusion

no code implementations24 May 2022 Roman Jacome, Jorge Bacca, Henry Arguello

To overcome this issue, compressive spectral image fusion (CSIF) employs the projected measurements of two CSI architectures with different resolutions to estimate a high-spatial high-spectral resolution.

JR2net: A Joint Non-Linear Representation and Recovery Network for Compressive Spectral Imaging

1 code implementation16 May 2022 Brayan Monroy, Jorge Bacca, Henry Arguello

Deep learning models are state-of-the-art in compressive spectral imaging (CSI) recovery.

Deep Low-Dimensional Spectral Image Representation for Compressive Spectral Reconstruction

1 code implementation IEEE 31st International Workshop on Machine Learning for Signal Processing (MLSP) 2021 Brayan Monroy, Jorge Bacca, Henry Arguello

This paper proposes an autoencoder-based network that guarantees a low-dimensional spectral representation through feature reduction, which can be used as prior in the compressive spectral imaging reconstruction.

Compressive Spectral Image Reconstruction using Deep Prior and Low-Rank Tensor Representation

1 code implementation19 Jan 2021 Jorge Bacca, Yesid Fonseca, Henry Arguello

The proposed method is based on the fact that the structure of some deep neural networks and an appropriated low-dimensional structure are sufficient to impose a structure of the underlying spectral image from CSI.
