    摘要： Systems and methods for the synthesis of light field images from virtual viewpoints in accordance with embodiments of the invention are disclosed. In one embodiment of the invention, a system includes a processor and a memory configured to store captured light field image data and an image manipulation application, wherein the captured light field image data includes image data, pixel position data, and a depth map, and wherein the image manipulation application configures the processor to obtain captured light field image data, determine a virtual viewpoint for the captured light field image data, where the virtual viewpoint includes a virtual location and virtual depth information, compute a virtual depth map based on the captured light field image data and the virtual viewpoint, and generate an image from the perspective of the virtual viewpoint based on the captured light field image data and the virtual depth map.

    摘要： A binary depth mask model is trained for use in occlusion within a mixed reality application. The training leverages information about virtual object positions and depths that is inherently available to the system as part of rendering of virtual objects. Training is performed on a set of stereo images, a set of binary depth masks corresponding to the stereo images, and a depth value against which object depth is evaluated. Given this input, the training outputs the binary depth mask model, which when given a stereo image as input outputs a depth binary depth mask indicating which pixels of the stereo image are nearer, or father away, than the depth value. The depth mask model can be applied in real time to handle occlusion operations when compositing a given real-world stereo image with virtual objects.

    摘要： The present application relates to the field of 3D images, and discloses a multi-viewpoint 3D display screen, comprising a display panel, comprising a plurality of composite pixels, wherein each composite pixel comprises a plurality of composite subpixels, and each composite subpixel comprises a plurality of subpixels corresponding to a plurality of viewpoints; and a plurality of gratings, parallelly arranged on the plurality of composite pixels, wherein each grating comprises a first oblique edge and a second oblique edge and is obliquely covered on the plurality of composite pixels, so that the first oblique edge and the second oblique edge intersect with the composite subpixels to define an inclination angle; in the composite subpixels, subpixels intersecting with or close to the first oblique edge form first terminal subpixels, and subpixels intersecting with or close to the second oblique edge form second terminal subpixels; and the inclination angle enables that: along an extension direction of the first oblique edge, colors of the first terminal subpixels, which are in at least a part of adjacent composite pixels and have the largest overlapping area with each grating, are different. According to the present application, the problems of red vignetting or vignetting of other colors in 3D display can be eliminated. The present application further discloses a multi-viewpoint 3D display terminal.
