1. Coloured Universe and the Russian Avant-Garde : Matiushin on Colour Vision in Stalin's Russia, 1932
Sammanfattning : Colour vision was of fundamental importance in modernist art. One reason its significance has been studied so little with regard to Russian art is that Soviet archives were inaccessible until the early 1990s. This work is the first close study on a so-called laboratory in an art- and science institute in the Soviet Union in the 1920s. LÄS MER
2. Shape from shading, colour constancy, and deutan colour vision deficiencies
Sammanfattning : Four studies including ten experiments adresses interrelations between some major and classical issues in visual perception: 3-D perception, colour constancy, colour perception and colour vision deficiencies. The main experimental paradigm to investigate the issues is within that of simulated shape from shading. LÄS MER
3. Diversity and Limits of Colour Vision in Terrestrial Vertebrates
Sammanfattning : Most terrestrial vertebrates have colour vision, some perceive a less colourful world and others actually discriminate a wider colour spectrum than humans do. Still, we can all make use of the valuable colour information, which is more rigid than just brightness. LÄS MER
4. Bird Vision: Spatial acuity and colour discrimination in bright and dim light
Sammanfattning : Birds use vision to guide navigation, foraging and mate choice, and studies of the limitations in bird visual perception are most helpful for the understanding of bird ecology. Here, I present four studies of bird vision in bright and dim light. LÄS MER
5. Colour Correction of Underwater Images Using Spectral Data
Sammanfattning : For marine sciences sometimes there is a need to perform underwater photography. Optical properties of light cause severe quality problems for underwater photography. Light of different energies is absorbed at highly different rates under water causing significant bluishness of the images. LÄS MER
