Colour and Directionality in Surface Reflectance
نویسنده
چکیده
1 The reflectance of light from the surface of an object is modelled by a new technique, using components extracted from a set of 64 images taken in an illumination dome, Techniques of photometric stereo are used to determine albedo and surface normals at each pixel. The ratio of actual to diffuse reflectance is modelled to find the specular angle and an angular distribution of intensity based on a Lorentzian function. Displaying images in a custom software viewer demonstrates the close appearance of the model to each original photograph when illuminated from the same angle.

Study of the effects of varying colours on industrial illumi-nation, human working and production model
In this paper, an attempt has been made to investigate the reflectance of various colours and effects of vary-ing colours on human working and production. Different colours have different reflectance and energy associ-ated with it. Colours play a significant role in the colour scheme of the houses, offices, factories etc. The col-ours may be seen on walls, tabletops, equipment, machines etc. In...
متن کاملPterin pigments amplify iridescent ultraviolet signal in males of the orange sulphur butterfly, Colias eurytheme.
Animal colouration is typically the product of nanostructures that reflect or scatter light and pigments that absorb it. The interplay between these colour-producing mechanisms may influence the efficacy and potential information content of colour signals, but this notion has received little empirical attention. Wing scales in the male orange sulphur butterfly (Colias eurytheme) possess ridges ...
متن کاملInvestigation of Directional Filter on Kube-Pentland’s 3D Surface Reflectance Model using Photometric Stereo
This paper uses theory, simulation and laboratory experiment to investigate the directional filter on Kube and Pentland’s linear reflectance model which presents the image directionality as a product of the illuminant direction and surface directionality. As a result, a surface rotation is not equivalent to an image rotation if the illuminant is not rotated. It can be seen that the directional ...
متن کاملColour Vision, Evolution, and Perceptual Content
Computational models of colour vision assume that the biological function of colour vision is to detect surface reflectance. Some philosophers invoke these models as a basis for 'externalism' about perceptual content (content is distal) and 'objectivism' about colour (colour is surface reflectance). In an earlier article (Thompson et al. 1992), I criticized the 'computational objectivist' posit...
متن کاملEffect of Surface Reflectance on Lighting Efficiency in Interiors
The paper attempts to analyze the relationship between surface colour reflectance and lighting power density for a given context. Analysis was based on digital modelling using validated lighting simulation tool. The study establishes itself on the premise that grey value of colour can be presumed to calibrate the luminous character of light. Also, it evaluates the impact of vertical and horizon...
