Although there has been significant progress in the past decade, tracking is still a very challenging computer vision task, due to problems such as occlusion and model drift. Recently, the increased popularity of depth sensors (e.g. Microsoft Kinect) has made it easy to obtain depth data at low cost. This may be a game changer for tracking, since depth information can be used to prevent model d...

Stereoscopic depth perception requires considerable neural computation, including the initial correspondence of the two retinal images, comparison across the local regions of the visual field and integration with other cues to depth. The most common cause for loss of stereoscopic vision is amblyopia, in which one eye has failed to form an adequate input to the visual cortex, usually due to stra...

diffusion of nitrogen in plasma nitrided iron and structural evolution during the nitriding process were evaluated by several characterization techniques including optical microscopy (om), microhardness depth profiling (hdp), scanning electron microscopy (sem), x-ray diffraction (xrd), glow discharge optical emission spectroscopy (gdoes), and secondary ion mass spectroscopy (sims). plasma nitri...

in this paper, surface and piezoelectric effects on the vibration behavior of nanowires (nws) are investigated by using a timoshenko beam model. the electric field equations and the governing equations of motion for the piezoelectric nws are derived with the consideration of surface effects. by the exact solution of the governing equations, an expression for the natural frequencies of nws with ...

statins are most effective pharmacologically agents to decrease total plasma cholesterol level by competitive inhibition of hmg-co a reductase. apart from the well-known ldl and cholesterol lowering effect, statins have been postulated to exert other beneficial effects also called pleotropic or non-lipid effects. better understanding of various pleotropic effects of statins has prompted a new s...

The question of whether defocus blur is a quantitative cue for depth perception is a topic of renewed interest. A recent study suggests that relative defocus blur can be used in computing depth throughout the visual field, particularly in regions where disparity loses precision. However, elements of the study's experimental design and theoretical analysis appear to undermine this claim. First, ...
