The system detects a camera viewpoint change between a current frame and a previous frame, decomposes a reconstructed depth map of the previous frame to a plurality of depth planes, adjusts the plurality of depth planes from a previous camera viewpoint to correspond with a current camera viewpoint, generates an MDP prediction by summing pixel values of the adjusted plurality of depth planes along a plurality of optical axes from the current camera viewpoint, determines an MDP prediction error between the MDP prediction and a depth map of the current frame, quantizes and codes the MDP prediction error, and transmits, to a receiver over a communication network, the camera viewpoint change and the coded quantized MDP prediction error for reconstruction of a depth map of the current frame.

Abstract: Systems and methods for rendering a 3D image are provided. The system receives texture and depth data (depth map) for an image. The system generates, based on the image data, a plurality of folded focal planes matrices. For each respective pixel matrix, the system preprocesses pixel values in the respective focal pixel plane matrix to generate a respective preprocessed matrix, wherein the respective preprocessed matrix clusters together pixel values of the respective folded focal plane matrix based on the depth data for the image. The system generates phase functions based on a plurality of the preprocessed matrices. The system configures a spatial light modulator of the SLM device in accordance with the generated phase functions. The system then provides the plurality of the preprocessed matrices as input to the SLM device to generate for display a 3D representation of the received image data.

Abstract: Systems and methods for reducing a number of focal planes used to display a three-dimensional object are disclosed herein. In an embodiment, data defining a three-dimensional image according to a first plurality of focal planes are received. Pixel luminance values from the first plurality of focal planes are mapped to a second plurality of focal planes comprising fewer focal planes than the first plurality of focal planes. Data is stored identifying initial focal distances of the mapped pixel luminance values in the first plurality of focal planes. The second plurality of focal planes are then displayed on a near eye device which uses the data identifying initial focal distances of the mapped pixel luminance values to adjust a wavelength of light produced by the second plurality of images to cause the pixels to appear at their original focal distances.

Abstract: A method and system for performing motion estimation in video image compression is provided. In the method and system, an associative memory device is used in motion estimation, and the group of the image blocks to be processed is restricted on the basis of a mean error and the best match is searched among the image blocks using the PDE method. The method and system can perform motion estimation via software in a regular PC environment and still more efficiently than before.
