Learning Representation in Colour Conversion

no code implementations1 Jan 2021 Arash Akbarinia, Raquel Gil-Rodriguez, Alban Flachot, Matteo Toscani

Our results show, with respect to the baseline network (whose input and output are RGB) 5-10% higher classification accuracy is obtained with decorrelating ColourConvNets.

Paradox in Deep Neural Networks: Similar yet Different while Different yet Similar

no code implementations12 Mar 2019 Arash Akbarinia, Karl R. Gegenfurtner

Machine learning is advancing towards a data-science approach, implying a necessity to a line of investigation to divulge the knowledge learnt by deep neuronal networks.

Manifestation of Image Contrast in Deep Networks

no code implementations12 Feb 2019 Arash Akbarinia, Karl R. Gegenfurtner

Contrast is subject to dramatic changes across the visual field, depending on the source of light and scene configurations.

How is Contrast Encoded in Deep Neural Networks?

no code implementations5 Sep 2018 Arash Akbarinia, Karl R. Gegenfurtner

Contrast is a crucial factor in visual information processing.

Colour Constancy: Biologically-inspired Contrast Variant Pooling Mechanism

no code implementations29 Nov 2017 Arash Akbarinia, Raquel Gil Rodríguez, C. Alejandro Parraga

Our experiments on three colour constancy benchmark datasets suggest that previous results can significantly improve by adopting a contrast-variant-pooling mechanism.

Colour Terms: a Categorisation Model Inspired by Visual Cortex Neurons

no code implementations19 Sep 2017 Arash Akbarinia, C. Alejandro Parraga

Although the neural substrate for this phenomenon is unknown, a recent study of cortical colour processing has discovered a set of neurons that are isoresponsive to stimuli in the shape of 3D-ellipsoidal surfaces in colour-opponent space.
