QMRNet: Quality Metric Regression for EO Image Quality Assessment and Super-Resolution

1 code implementation12 Oct 2022 David Berga, Pau Gallés, Katalin Takáts, Eva Mohedano, Laura Riordan-Chen, Clara Garcia-Moll, David Vilaseca, Javier Marín

Latest advances in Super-Resolution (SR) have been tested with general purpose images such as faces, landscapes and objects, mainly unused for the task of super-resolving Earth Observation (EO) images.

Hallucinating Saliency Maps for Fine-Grained Image Classification for Limited Data Domains

no code implementations24 Jul 2020 Carola Figueroa-Flores, Bogdan Raducanu, David Berga, Joost Van de Weijer

Most of the saliency methods are evaluated on their ability to generate saliency maps, and not on their functionality in a complete vision pipeline, like for instance, image classification.

MineGAN: effective knowledge transfer from GANs to target domains with few images

2 code implementations CVPR 2020 Yaxing Wang, Abel Gonzalez-Garcia, David Berga, Luis Herranz, Fahad Shahbaz Khan, Joost Van de Weijer

We propose a novel knowledge transfer method for generative models based on mining the knowledge that is most beneficial to a specific target domain, either from a single or multiple pretrained GANs.

A Neurodynamic model of Saliency prediction in V1

2 code implementations15 Nov 2018 David Berga, Xavier Otazu

Lateral connections in the primary visual cortex (V1) have long been hypothesized to be responsible of several visual processing mechanisms such as brightness induction, chromatic induction, visual discomfort and bottom-up visual attention (also named saliency).

Psychophysical evaluation of individual low-level feature influences on visual attention

1 code implementation15 Nov 2018 David Berga, Xosé Ramón Fdez-Vidal, Xavier Otazu, Víctor Leborán, Xosé María Pardo

In this study we provide the analysis of eye movement behavior elicited by low-level feature distinctiveness with a dataset of synthetically-generated image patterns.
