  2. 1. Appearance characterisation of textured polymeric surfaces

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

    Abstract : 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. READ MORE

  4. 2. Shape from shading, colour constancy, and deutan colour vision deficiencies

    Author : Torbjörn Jakobsson; Karl-Arne Gustafsson; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; 3-D perception; ambiguous figures; attached shadows; cast shadows; colour constancy; colour vision deficiency; deuteranomaly; deuteranopia; shape- from-shading;

    Abstract : 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. READ MORE

  5. 3. Appearance of textured and pigmented polymeric surfaces

    Author : Sofie Ignell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface texture; polymer; gloss; colour; perception; appearance;

    Abstract : The appearance is of increasing importance in the production of premium products since it is strongly connected to the quality impression. The surface appearance of any object may be described in terms of colour and surface characteristics such as gloss and texture. READ MORE

  6. 4. Appearance of Textured and Pigmented Polymeric Surfaces

    Author : Sofie Ignell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; appearance; perception; gloss; surface texture; polymer; colour;

    Abstract : The surface appearance is of great importance in the production of high-quality injection-moulded products since it is strongly connected to the quality impression. The surface appearance of any object may be described in terms of colour, gloss and texture. READ MORE

  7. 5. On Defect Generation and the Appearance of Injection-Moulded Polymers

    Author : Francesco Pisciotti; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; colour; gloss; ageing; rheology; defect; mechanical properties; surface topography; recycling; polypropylene; injection moulding; mass spectroscopy; simulation; polystyrene;

    Abstract : This thesis addresses the generation of some important manufacturing defects associated with intrinsic limitations of the injection moulding process. These include bulk-surface structural discontinuities, particularly air traps and welds, bulk-surface compositional inhomogeneities and gloss and colour variations. READ MORE
