In this paper, a procedure is described for the spatiotemporal segmentation and tracking of objects in colour image sequences. For this purpose, we propose the novel procedure of K-Means with connectivity constraint algorithm as a general segmentation algorithm combining several types of information including colour, motion and compactness. A new colour distance is also defined for this algorit...

The main thrust of this paper is to investigate the multi-scale retinex (MSR) approach to image enhancement to explain the effect of the processing from a theoretical standpoint. This leads to a new algorithm with fewer arbitrary parameters that is more flexible, maintains colour fidelity, and still preserves the contrast-enhancement benefits of the original MSR method. To accomplish this we id...

Recently, convergence of techniques used in image analysis and video processing has occurred. Many computation and memory intensive image analysis methods have become available for per frame processing of videos due to increased computing power of desktop computers and efficient implementations on multiple cores and graphical processing units (GPUs). As our main contribution in this work, we so...

The flipped classroom is an educational strategy about inverting the traditional use of in-class time for conducting lower-level learning activities and out-of-class time for conducting higher-level learning activities. Guided social inquiry learning (GSIL), which is a scaffolded constructivist pedagogic approach, has been conventionally adopted in learning and teaching of Liberal Studies (a “y...

Artists have different parameters to, for example, colour scientists, for considering the quality of the finished image. An analysis of the work is based on an artist's conception of the work and a subjective assessment of print surface, colour and image quality, which although may appear to be based on the same criteria as a reproduction, the impact on the viewer is quite different. This prese...

Using a widely used stellar population synthesis model, we study the ability of using pairs of AB system colours to break the well-known stellar age–metallicity degeneracy and give constraints on the two stellar-population parameters (age and metallicity). The relative age and metallicity sensitivities of AB system colours that relate to u, B, g, V , r, R, i, I, z, J , H , and K bands are prese...

Specific colours observed in images of the ocular fundus depend on the architecture of its layers and the optical properties and quantities of any pigments present. These colours can be predicted from the parameters describing the ocular tissue composition using a physics-based model of light transport. This paper reports preliminary results of the application of the inverse process by which th...

The interpretation of colour images is presented as an inverse problem in which a mapping is sought between image colour vectors and the physiological parameters characterizing a tissue. To ensure the necessary one-to-one correspondence between the image colours and the parameters, the mapping must be unique. This can be established through testing the sign of the determinant of the Jacobian ma...

A fully automatic colour texture editing method is proposed, which allows to synthesise and enlarge an artificial texture sharing anticipated properties from its parent textures. The edited colour texture maintains its original colour spectrum while its frequency is modified according to one or more target template textures. Edited texture is synthesised using a fast recursive model-based algor...
