The typical account of simultaneous contrast is that the contrast phenomenon occurs between two or more color surfaces seen together, thus affecting one another. LÄS MER

3. 2. It's All in the Brain : A Theory of the Qualities of Perception

   Författare :Jesper Östman; Pär Sundström; Howard Robinson; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Philosophy of perception; philosophy of consciousness; hallucination; phenomenal qualities; qualia; sense data; physicalism; Russell; disjunctivism; representationalism; brain theory; color; the brain; Theoretical Philosophy; teoretisk filosofi;

   Sammanfattning : This dissertation concerns the location and nature of phenomenal qualities. Arguably, these qualities naively seem to belong to perceived external objects. However, we also seem to experience phenomenal qualities in hallucinations, and in hallucinations we do not perceive any external objects. LÄS MER

4. 3. Texture and color of potato products

   Författare :Sandra Segnini; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; potato processing; sensory evaluations; L*a*b*; French fries; potato chips; Texture; color; Food and drink technology; Livsmedelsteknik;

   Sammanfattning : Texture and color are the most important parameters in the definition of the quality of potato products, but usually their subjective measurements do not give any reproducible results due to the complicating factors related to human perception. In order to understand the factors that can affect the texture and the color of the potato products during processing, instrumental techniques have been developed for quantifying those parameters.

7. 5. Evaluating and Improving Rendered Visual Experiences : Metrics, Compression, Higher Frame Rates & Recoloring

   Författare :Pontus Ebelin; Matematik LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Graphics; Image Quality Assessment; Perception; Edge Detection; Low Dynamic Range Imagery; High Dynamic Range Imagery; High Frame Rates; Texture Compression; Color Vision Deficiency; Recoloring; Computer Graphics; Image Quality Assessment; Perception; Edge Detection; Low Dynamic Range Imagery; High Dynamic Range Imagery; High Frame Rates; Texture Compression; Color Vision Deficiency; Recoloring;

   Sammanfattning : Rendered imagery is presented to us daily. Special effects in movies, video games, scientific visualizations, and marketing catalogs all often rely on images generated through computer graphics. However, with all the possibilities that rendering offers come also a plethora of challenges. LÄS MER
