Image coding with iterated contourlet and wavelet transforms
This paper presents a new coding technique based on a mixed contourlet and wavelet transform. The redundancy of the transform is controlled by using the contourlet at fine scales ...

FM halftoning via block error diffusion
Error diffusion halftoning is a popular method of producing frequency modulated (FM)halftones. In FM halftoning the dot size and shape is fixed (equal to one pixel) and the dot fr...

User-Defined B-Spline Template-Snakes
We combine a new user initialization process with a B-spline snake to create a model with the properties of a deformable template. This `template' snake can be constrained by ...

A watermarking-based method for single-channel audio source separation
In this paper, we address the issue of audio source separation with a single channel, i.e. the estimation of source signals from a single mixture of these signals. This problem is...

State Visibility and Communication in Unifying Theories of Programming
We explore the interactions between programvariable state visibility and communication behaviour in state-rich CSP-like processes, using the Unifying Theories of Programming (UTP)...
