Abstract: Methods for virtual clothes fitting when shopping online are presented. The online shopper prepares and keeps a 3D volumetric scan or point cloud of their body. Shoppers upload their 3D volumetric body scan to an online store. The online store stores the 3D volumetric scan of the clothing it offers for sale on their online shop. The online store has the processing capabilities to fit the 3D body scan provided by the shopper with the 3D volumetric scan of clothing it offers for sale on their online shop. Once the 3D volumetric data of the offered clothing item is digitally fitted by the online store on the 3D volumetric scan of the offered clothing item, the 3D volumetric data of the offered clothing fitted on the created “Virtual Mannequin” of the shopper is sent back to shopper to view and examine. On the screen of their computing platform, the shopper can then view and examine 3D images received (uploaded) from the online shop of the selected clothing item fitted on their virtual mannequin and make a buy decision.

Abstract: Methods and systems for light field image encoding and decoding are disclosed. According to some embodiments, scene metadata and input light field images associated with a scene are received. A first encoding operation is performed on the scene metadata and input light field images to generate reference images, reference disparity information, and an order of reference views. A second encoding operation is performed based on the reference images and reference disparity information to output light field encoded data. The light field encoded data includes the encoded reference images, the encoded reference disparity information, and the order of reference views. The light field encoded data is transmitted.

Abstract: A III-V light emitting device with pixels (mesa regions) specifically designed to enable lower cost through layer vias is disclosed for reduced cost of manufacture of the device. Reduction of cost of manufacture is achieved by having non-uniform width trench regions formed during pixel etch for the multi-pixel array part of the device. Through-layer vias are specifically formed in the wider part of the trench regions using cheaper lithography toolset enabled by the larger via critical dimension achievable in the wider part of the trench regions (as compared to narrow part of the trench regions). Larger via critical dimension enables improved electrical (and consequently optical) performance of the device due to better overlay control as well as lower via resistance.

Abstract: A compression method for high-resolution light field display is disclosed for applications in which computer memory constraints and latency are critical. The disclosed compression algorithm takes advantage of the 3D structure of a light field to compress the raw light field information with a fixed compression ratio and simple decoding instructions. The compressed high-resolution light field achieves a reduced bandwidth with acceptable quality, and is packed in a way that can be transmitted using common interfaces. In a preferred embodiment, the compression algorithm is used as a post-processing stage after light field information acquisition or after rendering. In a further preferred embodiment, the compression algorithm is incorporated into the acquisition or rendering procedure to reduce memory and rendering processing. These and further embodiments generate a compressed light field with all information required for direct display.

Abstract: Methods and systems for light field image encoding and decoding are disclosed. According to some embodiments, the method receives scene metadata and input light field images associated with a scene. The method further performs a first encoding operation on the scene metadata and the input light field images to generate reference views and reference disparity information. The method further performs a second encoding operation based on the reference views, the reference disparity information, and synthesized residuals to output encoded light field data, where the encoded light field data comprises encoded reference views, encoded reference disparity information, and encoded synthesized residuals. The method further randomly accesses and selects a group of reference views and corresponding disparity information from the encoded light field data based on one or more selected regions of interest. And the method transmits the selected group of reference views, the selected corresponding disparity information, and the encoded synthesized residuals.

Abstract: An emissive quantum photonic imager comprised of a spatial array of digitally addressable multicolor micro pixels. Each pixel is an emissive micro optical cavity comprising a monolithic color-tunable semiconductor light emitting diode. The light generated by each color-tunable pixel diode is emitted perpendicularly to the plane of the imager directly or via a plurality of vertical waveguides that extract and collimate the light generated from the pixel diode. Each pixel diode is individually addressable to enable the pixel to emit any of the colors associated with its monolithic color-tunable semiconductor light emitting diode at any on/off duty cycle for each color. The individual pixels modulate their required colors and brightness values by controlling the drive current and/or on/off duty cycle of the respective color-tunable diodes. Pixel-level micro optics further collimate and directionally modulate the light emitted from the micro pixels.
