Enhanced Hyperspectral Image Super-Resolution via RGB Fusion and TV-TV Minimization

1 code implementation13 Jun 2021 Marija Vella, BoWen Zhang, Wei Chen, João F. C. Mota

Such methods, however, cannot guarantee that the input measurements are satisfied in the recovered image, since the learned parameters by the network are applied to every test image.

Overcoming Measurement Inconsistency in Deep Learning for Linear Inverse Problems: Applications in Medical Imaging

1 code implementation29 Nov 2020 Marija Vella, João F. C. Mota

We then propose a framework that post-processes the output of DNNs with an optimization algorithm that enforces measurement consistency.

Robust Single-Image Super-Resolution via CNNs and TV-TV Minimization

1 code implementation2 Apr 2020 Marija Vella, João F. C. Mota

Single-image super-resolution is the process of increasing the resolution of an image, obtaining a high-resolution (HR) image from a low-resolution (LR) one.

Multimodal Image Super-resolution via Joint Sparse Representations induced by Coupled Dictionaries

1 code implementation25 Sep 2017 Pingfan Song, Xin Deng, João F. C. Mota, Nikos Deligiannis, Pier Luigi Dragotti, Miguel R. D. Rodrigues

This paper proposes a new approach to construct a high-resolution (HR) version of a low-resolution (LR) image given another HR image modality as reference, based on joint sparse representations induced by coupled dictionaries.

X-ray image separation via coupled dictionary learning

no code implementations20 May 2016 Nikos Deligiannis, João F. C. Mota, Bruno Cornelis, Miguel R. D. Rodrigues, Ingrid Daubechies

In support of art investigation, we propose a new source sepa- ration method that unmixes a single X-ray scan acquired from double-sided paintings.
