, 2008 This chapter presents a novel and generic framework for image segmentation using a compound image descriptor that encompasses both colour and texture information in an adaptive fashion. The developed image segmentation method extracts the texture information using low-level image descriptors (such as the Local Binary Patterns (LBP)) and colour ...

Spectrophotometric and Digital Colour Colourimetric (DCC) analysis of colour-based indicators [PDF]
Sensors and Actuators B: Chemical, 2018 Abstract Seven simulated absorption spectra that span the visible spectrum, are used to probe the degree of linear correlation that exists between real absorbance, Ao, at λmax, and three well-established colour-based parameters, based on the standard Red, Green and Blue scale, sRGB, namely: (i) apparent absorbance, A(sRGB), (ii) apparent fraction of ...

Factorial Analysis of Colour Vision [PDF]
Nature, 1946 HOUSTOUN1 has pointed out that a three-colour theory, such as that of Young and Helmholtz, inevitably leads to mathematical contradictions. It is well known in addition that a theory in which there are only three primary sensitivities, such as red, green and blue, becomes unsatisfactory when the many different forms of defective colour vision are ...

Analysis of colour moiré phenomenon in colour space
Periodica Polytechnica Mechanical Engineering, 2008 Moire topographic technique is widely used for three-dimensional surface reconstruction. One of the main problems is determination of the absolute order of a fringe for finding the depth difference between two points in moire patterns, i. e. convex and concave surfaces distinction.
