The slow speed of neural transmission necessitates that cortical visual information from dynamic scenes will lag reality. The "perceiving the present" (PTP) hypothesis suggests that the visual system can mitigate the effect of such delays by spatially warping scenes to look as they will in ~100 ms from now (Changizi, 2001). We here show that the Hering illusion, in which straight lines appear b...

Existing line segment detectors tend to break up perceptually distinct line segments into multiple segments. We propose an algorithm for merging such broken segments to recover the original perceptually accurate line segments. The algorithm proceeds by grouping line segments on the basis of angular and spatial proximity. Then those line segment pairs within each group that satisfy unique, adapt...

A novel and eecient generalized feature extraction method is presented based on the Expansion Matching (EXM) method and the Karhunen-Loueve (KL) transform. The EXM method is used to design optimal detectors for diierent features. The KL representation is used to deene an optimal basis for representing these EXM feature detectors with minimum truncation error. Input images are then analyzed with...

In this paper, a derivation and comparison of trellis-based multi-user detectors based on the so-called Forney metric and the Ungerboeck metric, respectively, is presented. Full-state detection (JMLSE) and reduced-state detection (JDDFSE) is considered. Similar to the corresponding single-user detectors, the performance of both full-state detectors is the same. In case of reduced-state detectio...

Thermoacoustic computed tomography (thermoacoustic CT) has thepotential to become a mayor non-invasive medical imaging method. Inthis paper we derive a general mathematical framework of a novel mea-suring setup introduced in [5]. It takes measuring data of line detectorsand offers better imaging resolution than conventional approaches basedon point-data approximation. We...

background: estimating dosimetric parameters for small fields under non-reference conditions leads to significant errors if done based on conventional protocols used for large fields in reference conditions. hence, further correction factors have been introduced to take into account the influence of spectral quality changes when various detectors are used in non-reference conditions at differen...

I compare two birth-cohorts of married women and find that divorce-risk plays a significantly smaller role in the recent cohort’s labor supply decision. This suggests that any decline in America’s divorce rates will not substantially reduce married women’s labor supply.  2000 Elsevier Science S.A. All rights reserved.

In response to disparate advances in delivering spatial information to support agricultural extension activities, the Extension Activity Support System (EASY) project was established to develop a vision statement and conceptual design for such a system based on a national needs assessment. Personnel from across Australia were consulted and a review of existing farm information/management softwa...
