    摘要： Layered depth image (LDI) and other more complicated 3D formats contain color, depth, and/or alpha channel information for visible pixels (base layer) and occluded pixels (occluded layers) of 3D video data. The present principles form 2D+depth/2D+delta representation using the information for the visible pixels, and embed the information for the occluded pixels into the 2D+depth/2D+delta content. When embedding, the occluded pixels that are more likely to be viewed from other view angles or used in multiple viewpoint video rendering are provided with stronger protection from transmission or compression errors. In one example, watermarking based on Least Significant Bit (LSB) and Spread Spectrum Watermarking (SSW) is used to illustrate the embedding process and the corresponding extraction process.

    摘要： A ring light source system for an interferometer with adjustable ring radius and ring radial width may comprise a laser light source, an expander and collimator optical system, an adjustable aperture, a binary phase grating, a variable-focus optical system, and a spatial filter. The expander and collimator optical system is configured to convert a light beam from the light source into a parallel light beam. The adjustable aperture is configured to adjust a diameter of the parallel light beam. The light beam with the diameter adjusted by the adjustable aperture is incident perpendicularly onto the binary phase grating, followed by the variable-focus optical system. The filter is positioned on a back focal plane of the variable-focus optical system, and is configured to receive a ring light source. The ring radius and radial width of the light source are adjustable by adjusting a focus length f1 of the variable-focus optical system.
