We present an interactive approach to the pseudo-colouring of greyscale images. We implement the technique by computing mappings from a three-dimensional (3D) colour space to a one-dimensional greyscale space (i.e. R 3 to R). To compute our maps, we employ both linear and nonlinear interpolation in 3D colour space. We validate our work by applying our maps… (More)
• iii Welcome It is with great pleasure that we warmly welcome you to the First Southern African Bioinformatics Workshop in the summer of 2007 at the University of the Witwatersrand in Johannesburg. Wits Bioinformatics is pleased to host this inaugural workshop. As a discipline, bioinformatics is still relatively young in South Africa and we were encouraged… (More)
When two variables are related by a known function, the coefficient of determination (denoted R2) measures the proportion of the total variance in the observations explained by that function. For linear relationships, this is equal to the square of the correlation coefficient, ρ. When the parametric form of the relationship is unknown, however, it is… (More)
