In accordance with various embodiments herein, disclosed herein is an apparatus comprising an imaging probe-based device operably linked to an automated tracking system. Furthermore, in various embodiments, the apparatus may be used to track the position and movement of a handheld imaging probe, including with respect to a subject's 3D surface profile. In one embodiment, a device may be used to track the position and movement of a handheld imaging probe with respect to a subject's 3D surface profile, while simultaneously acquiring optical data.

Motion tracking apparatus and method

A projector configured to provide higher resolution output without increasing pixel resolution in a light modulator is disclosed. The projector may introduce an optical element between a light modulator and an imaging lens. The optical element may provide pixel sharing of a target image. The pixel sharing may be produced by, for example, making smaller copies of pixels. Selected copies of pixels may be passed to the imaging lens to display an output image with selected areas of higher density pixels.

Projector with enhanced resolution via optical pixel sharing

A method includes generating in a computer a representation for the color transfer function both direct and inverse, of a nonideal source device to those in a target device significantly different than the source device, using higher-dimensional Bezier patches by using a non-linear parameterization of the Bezier patches in the XYZ space for converting the RGB colors in the source device. The method is illustrated in an application for processing spatial variation in luminance and chrominance in a multiple projector display, which include the steps of balancing per projector white point, morphing per pixel chrominance gamut, constraining per pixel perceptual luminance; and smoothing per pixel Bezier based luminance.
