On polymorphic logical gates in subexcitable chemical medium (2011)
Journal Article

In a subexcitable light-sensitive Belousov-Zhabotinsky (BZ) chemical medium an asymmetric disturbance causes the formation of localized traveling wave-fragments. Under the right conditions these wave-fragments can conserve their shape and velocity ve... Read More about On polymorphic logical gates in subexcitable chemical medium.

Towards arithmetic circuits in sub-excitable chemical media (2011)
Journal Article

A sub-excitable Belousov-Zhabotinsky medium exhibits localized travelling excitations (in contrast to an excitable medium exhibiting target or spiral waves). Initially assymetric perturbations give birth to excitation wave-fragments. The shape and ve... Read More about Towards arithmetic circuits in sub-excitable chemical media.

Enhancement of multi-user teleoperation systems by prediction of dyadic haptic interaction (2010)
Presentation / Conference Contribution

Adaptive cancelation of self-generated sensory signals in a whisking robot (2010)
Journal Article

Sensory signals are often caused by ones own active movements. This raises a problem of discriminating between self-generated sensory signals and signals generated by the external world. Such discrimination is of general importance for robotic system... Read More about Adaptive cancelation of self-generated sensory signals in a whisking robot.

MOBISERV: An integrated intelligent home environment for the provision of health, nutrition and mobility services to the elderly (2010)
Presentation / Conference Contribution

Life expectancy increases and the wish to prolong independent living remains strong. To stay as independent as possible gives satisfaction to the individual and reduces costs for society. With advances in information and communication technologies, s...

High speed, multi-scale tracing of curvilinear features with automated scale selection and enhanced orientation computation (2010)
Presentation / Conference Contribution

We propose a new high speed line tracing algorithm based on a well known differential geometric line extraction algorithm. The previously separate steps of line detection and line tracing are performed simultaneously. This allows the exclusion of non...

An efficient and practical 3D face scanner using near infrared and visible photometric stereo (2010)
Presentation / Conference Contribution

This paper is concerned with the acquisition of model data for automatic 3D face recognition applications. As 3D methods become progressively more popular in face recognition research, the need for fast and accurate data capture has become crucial. T...

Biologically inspired 3D face recognition from surface normals (2010)
Presentation / Conference Contribution

A major consideration in state-of-the-art face recognition systems is the amount of data that is required to represent a face. Even a small (64 × 64) photograph of a face has 2 12 dimensions in which a face may sit. When large (> 1MB) photographs of...

Multi-scale depth from slope with weights (2010)
Presentation / Conference Contribution

We describe a robust method to recover the depth coordinate from a normal or slope map of a scene, obtained e.g. through photometric stereo or interferometry. The key feature of our method is the fast solution of the Poisson-like integration equation... Read More about Multi-scale depth from slope with weights.

Stochastic automated search methods in cellular automata: The discovery of tens of thousands of glider guns (2010)
Journal Article

This paper deals with the spontaneous emergence of glider guns in cellular automata. An evolutionary search for glider guns with different parameters is described and other search techniques are also presented to provide a benchmark. We demonstrate t...

Safe adaptive compliance control of a humanoid robotic arm with anti-windup compensation and posture control (2010)
Journal Article

Safety is very important for physical human-robot interaction. Compliance control can solve an important aspect of the safety problem by dealing with impact and other forces arising during close contact between humans and robots. An adaptive complian...

3D face reconstructions from photometric stereo using near infrared and visible light (2010)
Journal Article

This paper seeks to advance the state-of-the-art in 3D face capture and processing via novel Photometric Stereo (PS) hardware and algorithms. The first contribution is a new high-speed 3D data capture system, which is capable of acquiring four raw im...
