Abstract: An example apparatus for calibrating depth cameras includes an image receiver to receive an image from a depth camera. The apparatus also includes an object detector to detect a natural object with an expected shape in the image. The apparatus further includes a parameter adjuster to adjust a parameter of the depth camera to reduce a detected difference between the expected shape and a measured characteristic of the natural object.

Abstract: In one example, a head-mounted display (HMD) device includes a laser pattern generator to generate a pattern that is directed into an eye and reflected off of a retina and back out of the eye. A camera is included to capture an image of a reflected pattern from the retina. A pattern analyzer is included to determine a point spread function for the eye from the reflected pattern and to determine a focus plane for a user from the point spread function. A rendering engine renders the content on a display, wherein content at the focus plane is rendered at a higher resolution of the display, and content not at the focus plane is rendered at a lower resolution for the display.

Abstract: Techniques for tuning the illumination pattern of a Light Emitting Diode (LED) are described. An example image capture system incorporates an LED with an integrated micro-reflector. The example image capture system includes a camera to capture an image of an object and a Light Emitting Diode (LED) to emit light for illuminating the object. The LED includes a light emitting layer and a window layer made of transparent semiconductor material disposed over the light emitting layer. The shape of the window layer creates a plurality of reflectors that generate a specified illumination pattern that reduces the effect of illuminance distortions created by the image capture system.

Abstract: High dynamic range depth generation is described for 3D imaging systems. One example includes receiving a first exposure of a scene having a first exposure level, determining a first depth map for the first depth exposure, receiving a second exposure of the scene having a second exposure level, determining a second depth map for the second depth exposure, and combining the first and second depth map to generate a combined depth map of the scene.

Abstract: A system is provided for increasing the brightness and color saturation of a liquid crystal display to permit direct sunlight viewing which includes the utilization of an array of diffractive color separation microlenses which serve both to spatially separate incoming white light into red, green and blue bands which do not overlap and to focus the bands onto a subpixel matrix such that each of the sub-pixels is illuminated with only one color. The diffractive color separation is made possible through the utilization of the iterative genetic algorithm which specifies the stepped surface of the lens that provide for exceptionally fine color separation. In one embodiment the genetic algorithm is applied iteratively to define the optimal stepped surfaces which are utilized to focus the various colors at different positions at the focal plane of the lens. The subject system improves the overall transmission efficiency of 5% for a standard liquid crystal display to in excess of 30% overall efficiency.

Abstract: A trimodal microlens configuration is provided for the lenses in a microlens array utilized as a diffraction separator for generating separated bands of different color when the microlens array is provided with a collimated light source. To provide the trimodal functionality, each microlens is divided up into three segments, with the center segment providing a red, green, blue diffraction pattern, with the left segment providing a blue, red, green diffraction pattern, and with the right segment providing a green, blue, red diffraction pattern. This pattern is directed towards an adjacent liquid crystal color display in which its sub-pixels are arranged red, green, blue, with the green sub-pixel aligned with the center segment of the corresponding lens.

Abstract: A process, known as the Hick's Probabilistic Data Association Algorithm, correlates sensor measurement to target tracks under condition in which there are numerous false measurements. It accomplishes this by forming multiple hypotheses and computing a probabilistic score for each. The hypothesis with the high score is then used as a probability vector to update each target's track. The result is accomplished by combining the attributes of Joint Probabilistic Data Association (JPDA) and Nearest Neighbor Standard Filter (NNSF). This combination provides an improved algorithm which yields improved performance ever both prior art methods under high clutter conditions with crossing targets.
