Some Experiments on Colour

Experiments in colour texture analysis

In this paper we focus on the classi®cation of colour texture images. The main objective is to determine the contribution of colour information to the overall classi®cation performance. Three relevant approaches to grey scale texture analysis, namely local linear transforms, Gabor ®ltering and the co-occurrence approach are extended to colour images. They are evaluated in a quantitative manner ...

Some Randomness Experiments on TRIVIUM

This paper develops two methods for exploring the structure of the stream cipher TRIVIUM. We consider whether it is possible to compute the algebraic normal form (ANF) of such functions. Since the key and the IV together make up 160 variables, doing this directly is not possible. Instead, one can choose a subset of the key and IV variables of size n and fix the other variables to constants. As ...

Experiments in inkjet colour tests for printmaking

The motivation for this research is based on how artists mix and print colour by traditional means (painting and printmaking) and how these differ from colour picker tools, slider bars and methods developed for digital printing, and whether it is possible to incorporate both? Artists have been expert at mixing colour for centuries, yet although the artist and designer has access to a wide range...

Some Experiments on Idiolectal Differences among Speakers

It is generally recognized that human listeners can distinguish between speakers who are familiar to them far better than those who are unfamiliar. This increased ability is due no doubt to speaker idiosyncrasies that are recognized by the listener, either consciously or unconsciously. These speaker characteristics offer the possibility to significantly improve automatic speaker recognition per...
