This paper addresses the problem of using appearance and motion models in classifying and tracking objects when detailed information of the object’s appearance is not available. The approach relies upon motion, shape cues and colour information to help in associating objects temporally within a video stream. Unlike previous applications of colour in object tracking, where relatively large-size ...

The colour-matching functions of standard observers proposed by the CIE represent the normal colour vision for the worldwide population. But there are deviations in the colourmatching functions for real observers with a normal colour vision, so the observer metamerism index was defined by CIE to evaluate the mismatch between them in colour appearance. In this work, we present an alternative for...

This paper points out that achievements in the field of multimedia analysis and retrieval represent an important opportunity for improvement of recommender system mechanisms. Online shopping systems use various recommender systems; however a study of different approaches has shown that they do not exploit the potential of information carried by multimedia product data for product recommendation...

A model of colour formation within human skin has been developed to aid the characterisation of pigmented skin lesions from their digitized colour images. The model is based on the Kublenka–Munk theory of scattering and absorption within inhomogeneous materials and the physics pertaining to their colour properties. By considering the skin to be a layered construction of such materials, the stra...

Subjective colour spaces were reconstructed for persons occupationally exposed to mercury (Hg) and patients with diabetes mellitus type 2 (DM-2), two groups at risk for acquired colourvision deficiency, and compared with healthy normal trichromats. Judgments of colour dissimilarity were collected with the method of triads, applied to a composite assortment of colour samples. These were drawn fr...

We consider a model of a discrete time “interacting particle system" on the integer line where infinitely many changes are allowed at each instance of time. We describe the model using chameleons of two different colours, viz., red (R) and blue (B). At each instance of time each chameleon performs an independent but identical coin toss experiment with probability α to decide whether to change i...

Colour mixing by a halftoning process, as used for colour reproduction in graphic arts and many forms of digital hardcopy, is neither additive nor subtractive. Halftone colour reproduction with a given set of primary colours is heavily influenced not only by the colourimetric properties of the full-tone primaries, but also by effects such as optical and physical dot gain and the halftone geomet...

Organisms capable of rapid physiological colour change have become model taxa in the study of camouflage because they are able to respond dynamically to the changes in their visual environment. Here, we briefly review the ways in which studies of colour changing organisms have contributed to our understanding of camouflage and highlight some unique opportunities they present. First, from a prox...
