Imaging devices exploit the Nyquist-Shannon sampling theorem to avoid both aliasing and redundant oversampling by design. Conversely, in medical image resampling, images are considered as continuous functions, are warped by a spatial transformation, and are then sampled on a regular grid. In most cases, the spatial warping changes the frequency characteristics of the continuous function and no ...

The Quantization Theorem I (QT I) implies that the likelihood function can be reconstructed from quantized sensor observations, given that appropriate dithering noise is added before quantization. We present constructive algorithms to generate such dithering noise. The application to maximum likelihood estimation (mle) is studied in particular. In short, dithering has the same role for amplitud...

Value Prediction is one of the newest techniques used to break down ILP limits. Despite being under continuous study during the last few years, a few aspects related to this emerging technique remain unanalysed in depth. Exhaustively investigated in the context of control speculation, confidence estimation has usually played a secondary role on value prediction and speculation. Closely linked t...

In this paper we propose a new strategy for the design of real-valued lterbanks which avoids aliasing in the subbands (\inband aliasing") such that applications where two subband signals have to be compared become possible. One example for such an application is subband adap-tive ltering, where, with the proposed lter-bank structure, the traditionally required cross-term adaptive lters between ...

Aliasing environments present the tasks of increased difficulty for Learning Classifier Systems. Aliasing squares look identical for an agent with limited perceptive power, but may demand a completely different optimal strategy. Thus, the presence of aliasing squares in a maze may lead to a non-optimal behaviour and decrease the agent’s performance. As a possible approach to the problem we intr...

Many problems correspond to the classical control task of determining the appropriate control action to take, given some (sequence of) observations. One standard approach to learning these control rules, called behavior cloning, involves watching a perfect operator operate a plant, and then trying to emulate its behavior. In the experimental learning approach, by contrast, the learner rst guess...

This paper describes a new parallel architecture for perfonning high-speed raster graphics. This architecture relies on an extension of the Z-buffer algorithm called Composition, due to Duff. Duff's algorithm proves to be too complex for our implementation technology, so modifications of Duff's algorithm are introduced and evaluated experimentally. The two major issues addressed are anti-aliasi...
