This paper presents a new background subtraction algorithm for mobile objects segmentation from a static background scene. Firstly, a case analysis of colour-motion segmentation problems is presented. Secondly, an architecture which fuses colour, intensity and edge cues is developed to cope the motion segmentation problems presented in the case analysis. Our approach first combines both colour ...

In this paper, we present an optimised learning algorithm for learning the parametric prior models for high-order Markov random fields (MRF) of colour images. Compared to the priors used by conventional low-order MRFs, the learned priors have richer expressive power and can capture the statistics of natural scenes. Our proposed optimal learning algorithm is achieved by simplifying the estimatio...

We add a simple model for spatial vision to our original corresponding pair algorithm to simulate the colour appearance of an image, as seen by a subject with variant (abnormal) vision. In this way, the perception of coloured images by subjects having their spatial vision altered by a pathology, may be simulated, both for normal and dichromatic colour vision. Introduction Acquired vision defect...

We investigate the radial colour gradient and two-dimensional (2D) colour properties of 22 E+A galaxies with 5.5Å < Hδ EW < 8.5Å and 49 normal early-type galaxies as a control sample at a redshift of < 0.2 in the Second Data Release of the Sloan Digital Sky Survey. We found that a substantial number of E+A galaxies exhibit positive slopes of radial colour gradient (bluer gradients toward the ce...

It is conceivable that there is an SU (N) ℓ 'colour' gauge group for leptons, analogous to the gauged SU (3) q colour group of the quarks. The standard model emerges as the low energy effective theory when the leptonic colour is spontaneously broken. The simplest such generalised leptonic colour models are constructed. We show that the seesaw mechanism for small neutrino masses, along with the ...

This article provides a proof-of-concept for using a biogeochemical/ecosystem/optical model with radiative transfer component as a laboratory to explore aspects of ocean colour. We focus here on the satellite ocean colour Chlorophyll-a (Chl10 a) product provided by the often-used blue/green reflectance ratio algorithm. The model produces output that can be compared directly to the real world oc...

Recently it has been argued that a three-body colour confinement interaction can affect the stability condition of a three-quark system and the spectrum of a tetraquark described by any constituent quark model. Here we discuss the role of a three-body colour confinement interaction in a simple quark model and present some of its implications for the spectra of baryons, tetraquarks and six-quark...
