  1. 11. Colour Vision in Birds : Comparing behavioural thresholds and model predictions

    Författare :Peter Olsson; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gallus gallus; receptor noise; visual modelling; animal training; colour discrimination; colour constancy;

    Sammanfattning : Birds use colour vision for many biologically relevant behaviours such as foraging and mate choice. Bird colour vision is mediated by four types of single cones, giving them an extra dimension of colour information compared to trichromatic humans. LÄS MER

  5. 14. On the evaluation of print mottle

    Författare :Carl-Magnus Fahlcrantz; Jan-Olof Eklundh; Jon Hardeberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mottle; Print quality; Texture; Image analysis; Perception; Computer science; Datalogi;

    Sammanfattning : Print Mottle is perhaps one of the most disturbing factors influencing overall Print Quality. Mottle has traditionally been evaluated by estimating the reflectance variation in the print. LÄS MER

  7. 15. Appearance characterisation of textured polymeric surfaces

    Författare :Ingrid Arino; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; appearance; reflectance; polymer; colour; surface texture; gloss;

    Sammanfattning : Appearance demands for industrial products are generally increasing since they are closely related to the overall quality impression. Consequently, there is a need to define appearance through its main descriptors, which are gloss, colour and surface texture, as well as the relations between them. LÄS MER
