There exists a large conceptual gap between symbolic models and emergent models for the
mind. Many emergent models work on low-level sensory data, while many symbolic models …

This paper presents a new approach to the extraction of the contour of a moving object. The
method is based on the fusion of a motion segmentation technique using image subtraction …

The dual-tree quaternion wavelet transform (QWT) is a new multiscale analysis tool for
geometric image features. The QWT is a near shift-invariant tight frame representation …

By examining the problem of image correspondence (binocular stereo and optical flow) and
its relationship with other modules such as segmentation, shape and depth estimation …

The analytic signal of a real signal is a standard concept in 1D signal processing. However,
the definition of an analytic signal for real 2D signals is not possible by a straightforward …

Abstract Fourier Mellin SOFT (FMS) as a novel method for global registration of 3D data is
presented. It determines the seven degrees of freedom (7-DoF) transformation, ie, the 6-DoF …

This thesis deals with focus of attention control in active vision systems. A framework for
hierarchical gaze control in a robot vision system is presented, and an implementation for a …

This paper describes the implementation of a stereo-vision system using Field
Programmable Gate Arrays (FPGAs). Reconfigurable hardware, including FPGAs, is an …

An efficient method of computing the least-squares optimal basis functions to steer any
function locally is presented. The method combines the Lie group-theoretic and the singular …
