Distinctive convergence in Australian floral colours seen through the eyes of Australian birds
We used a colour-space model of avian vision to assess whether a distinctive bird pollination syndrome exists for floral colour among Australian angiosperms. We also used a novel phylogenetically based method to assess whether such a syndrome represents a significant degree of convergent evolution. About half of the 80 species in our sample that attract nectarivorous birds had floral colours in...
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...

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....
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 کاملVersion of 2.5.99. CONTRAST COLOURS
‘So the judgements that we hold about the colours of objects seem not to depend uniquely on the absolute nature of the rays of light that paint the picture of objects on the retina; our judgements can be changed by the surroundings, and it is probable that we are influenced more by the ratio of some of the properties of the light rays than by the properties themselves, considered in an absolute...
