Spatio-temporal model for subjective colours based on colour coded ganglion cells
We propose a mathematical model for the generation of the subjective colour phenomenon through Benham's disk stimuli. The model relates to the spatial and temporal properties of three colour coded retinal ganglion cells: L+/M-, M+/L- and S-/(L+M)+ [or (L+M)-/S+]. It is suggested that the phenomenon is based on both the opponent mechanisms in the cells' receptive fields, and the "rebound respons...
متن کاملSpotting Colours
Spotting an object of a chosen colour, skin for example, in an image taken under uncontrolled lighting conditions requires some form of preprocessing to convert the image colours to an illumination-independent specification. Computational colour constancy algorithms are designed specifically to accomplish this task. We process images with different colour constancy algorithms and evaluate the r...
متن کاملSegmenting memory colours
Memory colours refer to the colour of specific image classes that have the essential attribute of being perceived in a consistent manner by human observers. In colour correction -or renderingtasks, this consistency implies that they have to be faithfully reproduced; their importance, in that respect, is greater than other regions in an image. Before these regions can be properly addressed, one ...
متن کاملTensors, colours, octahedra
Several theorems in combinatorial convexity admit colourful versions. This survey describes old and new applications of two methods that can give such colourful results. One is the octahedral construction, the other is Sarkaria’s tensor method.
متن کاملThe Expressions of Colours
A whole world is presented in front of the eyes of a gamer. This world has shapes and colours. What do colours transmit? Is this considered in digital games? These are the main issues of this work. We are part of a culture which has been decanting meanings for ages, including those of colours. These coded meanings are shared connotations of feelings, sensations, atmosphere, thoughts, and moods....
