The problem of removing illuminant variations to preserve the colours of objects (colour
constancy) has already been solved by the human brain using mechanisms that rely largely …

Edges are key components of any visual scene to the extent that we can recognise objects
merely by their silhouettes. The human visual system captures edge information through …

In this work, we simulate the early visual information processing mechanisms in biological
visual system (BVS) to solve the visible-infrared image fusion (VIIF) task. Concretely, both …

Pooling is a ubiquitous operation in image processing algorithms that allows for higher-level
processes to collect relevant low-level features from a region of interest. Currently, max …

The original idea of this project was to study the role of colour in the challenging task of
object recognition. We started by extending previous research on colour naming showing …

Although it seems counter-intuitive, categorical colours do not exist as external physical
entities but are very much the product of our brains. Our cortical machinery segments the …
