The first step in the interpretation of video sequences is the estimation of spatio-temporal image representations, that is the image motion or the correspondence of points or lines. Noise in the data, however, causes a serious problem for their estimation; in particular, it causes bias. As a result the location of image points, the orientation of image lines and the length and orientation of i...

INTRODUCTION Observation-based occupational safety programs have long recognized the critical interaction of environment and behaviour in the workplace [1]. While the veracity of these programs is questioned [2], their foundation in behavioural psychology connects to various theory-based paradigms for changing manual materials handling (and musculoskeletal loading, or `consequences`) by manipul...

Kinetic data for enzymes that do not obey MichaelisMenten kinetics have often been displayed in ways that suggest abrupt transitions between straight portions of double-reciprocal plots or other plots that are straight in the Michaelis-Menten case, a notable example being provided by glutamate dehydrogenase (EC 1.4.1.3) from cattle liver (Engel & Dalziel, 1969). Taken literally, such plots indi...

Wave Field Synthesis (WFS) is a sound reproduction technique using loudspeaker arrays that postpones the limits set by conventional techniques (stereo, 5.1 ...). These techniques rely on stereophonic principles allowing the creation of an acoustical illusion (as opposed to an optical illusion) over a very small area in the center of the loudspeaker setup, generally referred to as “sweet spot”. ...

BACKGROUND Dynamical systems like neural networks based on lateral inhibition have a large field of applications in image processing, robotics and morphogenesis modeling. In this paper, we will propose some examples of dynamical flows used in image contrasting and contouring. METHODOLOGY First we present the physiological basis of the retina function by showing the role of the lateral inhibit...
