Propagating wave segments are stabilized to a constant size and shape by applying negative feedback from the measured wave area to the excitability of the medium. The locus of steady-state wave size as a function of excitability defines the pertur...

Intricate patterns of wave propagation are exhibited in a chemical reaction-diffusion system with spatiotemporal feedback, Wave behavior is controlled by feedback-regulated excitability gradients that guide propagation in specified directions. Wav...

Experimental and theoretical studies of the excitability boundary for spiral wave behavior are presented. The boundary is defined by unstable wave segments, which are stabilized by using a negative-feedback control algorithm. A kinematic descripti...
We introduce a simple method for motion enhancement. The method enables us to realize brightness enhancement of moving objects, to reduce the influence of non-uniform illumination in motion analysis and to visualize dynamic streamlines in fluid fl...
