The purpose of this study was to measure the rate-dependent changes in the relative motion of subsynovial connective tissue (SSCT) and median nerve in the human carpal tunnel. Using fluoroscopy, we measured the relative motion of middle finger flexor digitorum superficialis tendon, SSCT, and median nerve in eight human cadavers during simulated active finger flexion motions at 2.0, 5.0, 7.5, an...

The quadrupole channel of two-photon double ionization of He exhibits two distinctly different modes of correlated motion of the photoelectron pair. The kinematics of the mode associated with the center-of-mass motion favors large total momenta maximized at parallel emission where the interelectron repulsion is strong. In contrast, the mode associated with the relative motion favors large relat...

Typical Structure-from-Motion systems spend major computational effort on geometric verification. Geometric verification recovers the epipolar geometry of two views for a moving camera by estimating a fundamental or essential matrix. The essential matrix describes the relative geometry for two views up to an unknown scale. Two-view triangulation or multi-model estimation approaches can reveal t...

A neurocomputational model is presented for gure-ground discrimination by relative motion. In the model, the correlation type of elementary motion detectors (EMDs), an oscillatory neural network for motion perception and a selective attention module are involved. It is shown that through the oscillatory amplitude and frequency encoding and selective synchronization of phase oscillators, a perfe...

This paper analyzes the important issues associated with structure computations through binocular motion when inertial navigation systems are used to nd the sensor motion parameters. In particular, we study the conditions under which the relative error in environmental depth is reduced through the use of binocular motion over the separate use of monocular motion and static stereo. The results o...

When two sets of intermixed dots move in different directions the perceived direction of each is considerably shifted [Marshak & Sekuler (1979). Science, 205, 1399-1401; Mather & Moulden, (1980). Quarterly Journal of Experimental Psychology, 32, 325-333)]. This phenomenon has been attributed to 'repulsive' interactions between channels tuned to different directions of motion. However, we report...

Technological advances of position aware devices lead to a wealth of data documenting the lifelines of GPS-tracked animals, people, or vehicles. The integration of knowledge discovery techniques in GIS is thus an important research field with respect to the emerging volumes of tracking data. The motivation of this research is to find patterns in the way such moving point objects (MPOs) move in ...

We propose simple and efficient methods for estimating the camera motion between two images when this motion is small. While current solutions are still either slow, or unstable in case of small translation, we show how to considerably speed up a recent stable but slow method. The reasons for this speed-up are twofold. First, by approximating the rotation matrix to first order, we obtain a smal...

A puzzling aspect of the hydrophobic attraction is that its intensity and range appear to be qualitatively different as concerns extended surfaces of large area and small molecules of modest size.1-4 One difference is fundamental: the hydrogen-bond network of water is believed for theoretical reasons to be less disrupted near a single alkane molecule than near an extended surface.1-4 A second d...
