  • High resolution free-view interpolation of planar structure
    Patent number: 9824486
    Abstract: A method and system is proposed to create a generative model to interpolate any view of a planar scene given a sequence of reference views and a synthesis view that is optimized by the marginalization of photometric regulation, and geometric registration parameters. According to one aspect of the claimed subject matter, a technique is proposed to combine information from varying input camera poses. Planar homography based image super resolution in free view interpolation for planar structure is applied to the combined information. Non-redundant information is combined in such a manner that the high resolution and free view problems in traditional 2D based image-based rendering techniques are overcome.

The core has a melting point higher than that of the sheath. The bottom layer fabric is disposed on one side of the top layer fabric. The support layer is disposed between the top layer fabric and the bottom layer fabric. As the core has a melting point higher than that of the sheath, the different-melting point fiber has superior dimensional stability and permanent shape memory after heat treatment for plastic shaping.

  • Fast decoding based on ZigZag deconvolution for random projection code
    Patent number: 9432056
    Abstract: Multi-level symbols generated by applying a Random Projection Code (RPC) to a source bit sequence are received at a receiver via a noisy channel. The received multi-level symbols are represented in a bipartite graph as constraint nodes connected via weighted edges to binary variable nodes that represent the source bit sequence. A decoder uses ZigZag deconvolution to generate constraint node messages as part of an iterative belief propagation to decode the source bit sequence from the received multi-level symbols.
