Harlequin Colour Change in the Newborn

Acta Obstetricia et Gynecologica Scandinavica, 1959
In 1952, Neligan and Strang described a previously unknown phenomenon in newborn babies, which they termed “liarlequin colour change”. This term has since been used in other reports on the condition but does not seem to be very appropriate; the colour change is not harlequin-like in the current sense of the word, since the modern harlequin wears a ...

Control of Colour Change in Amphibians

A System for Finding Changes in Colour

Procedings of the Alvey Vision Conference 1987, 1987
We acquire a great deal of information about the world about us by perceiving the colour of objects. We can manage without colour, but certain tasks can become rather difficult telling ripe from unripe fruits, or finding green tennis balls lost in grass, for example. Yet colour information is seldom used by the machine vision community, although, given
