Exploring Deep Learning Image Super-Resolution for Iris Recognition

no code implementations2 Nov 2023 Eduardo Ribeiro, Andreas Uhl, Fernando Alonso-Fernandez, Reuben A. Farrugia

In this work we test the ability of deep learning methods to provide an end-to-end mapping between low and high resolution images applying it to the iris recognition problem.

The Best of Both Worlds: a Framework for Combining Degradation Prediction with High Performance Super-Resolution Networks

1 code implementation Sensors 2023 Matthew Aquilina, Keith George Ciantar, Christian Galea, Kenneth P. Camilleri, Reuben A. Farrugia, John Abela

To date, the best-performing blind super-resolution (SR) techniques follow one of two paradigms: A) generate and train a standard SR network on synthetic low-resolution - high-resolution (LR - HR) pairs or B) attempt to predict the degradations an LR image has suffered and use these to inform a customised SR network.

Face2Text revisited: Improved data set and baseline results

no code implementations PVLAM (LREC) 2022 Marc Tanti, Shaun Abdilla, Adrian Muscat, Claudia Borg, Reuben A. Farrugia, Albert Gatt

To encourage the development of more human-focused descriptions, we developed a new data set of facial descriptions based on the CelebA image data set.

Super-Resolution for Selfie Biometrics: Introduction and Application to Face and Iris

no code implementations12 Apr 2022 Fernando Alonso-Fernandez, Reuben A. Farrugia, Julian Fierrez, Josef Bigun

Such techniques are designed to restore generic images and therefore do not exploit the specific structure found in biometric images (e. g. iris or faces), which causes the solution to be sub-optimal.

Improving Super-Resolution Performance using Meta-Attention Layers

1 code implementation IEEE Signal Processing Letters 2021 Matthew Aquilina, Christian Galea, John Abela, Kenneth P. Camilleri, Reuben A. Farrugia

While many such networks can upscale low-resolution (LR) images using just the raw pixel-level information, the ill-posed nature of SR can make it difficult to accurately super-resolve an image which has undergone multiple different degradations.

A Simple Framework to Leverage State-Of-The-Art Single-Image Super-Resolution Methods to Restore Light Fields

no code implementations27 Sep 2018 Reuben A. Farrugia, C. Guillemot

Super-resolving this principal basis using an SISR method allows us to super-resolve all the information that is coherent across the entire light field.

Face2Text: Collecting an Annotated Image Description Corpus for the Generation of Rich Face Descriptions

1 code implementation LREC 2018 Albert Gatt, Marc Tanti, Adrian Muscat, Patrizia Paggio, Reuben A. Farrugia, Claudia Borg, Kenneth P. Camilleri, Mike Rosner, Lonneke van der Plas

To gain a better understanding of the variation we find in face description and the possible issues that this may raise, we also conducted an annotation study on a subset of the corpus.

Light Field Super-Resolution using a Low-Rank Prior and Deep Convolutional Neural Networks

no code implementations12 Jan 2018 Reuben A. Farrugia, Christine Guillemot

Light field imaging has recently known a regain of interest due to the availability of practical light field capturing systems that offer a wide range of applications in the field of computer vision.
