Abstract: A method and an apparatus for generating a virtual viewpoint image by obtaining at least one input viewpoint image and warping pixels of the at least one input viewpoint image to a virtual viewpoint image coordinate system; mapping a patch to a first pixel of a plurality of pixels warped to the virtual viewpoint image coordinate system when a difference between a first depth value of the first pixel and a second depth value of a second pixel adjacent to the first pixel is less than or equal to a predetermined threshold and mapping no patch to the first pixel when the difference is greater than the predetermined threshold; and generating the virtual viewpoint image by blending the plurality of pixels and/or the patch are provided.

Abstract: A Faster-Than-Nyquist (FTN)-based transmitting apparatus segments an input data bit string into a plurality of partial bit strings, simultaneously channel-encodes each of the plurality of partial bit strings, simultaneously modulates each of the plurality of channel encoded bit strings to generate a plurality of modulation symbol sequences, and then pulse-shapes and transmits the plurality of modulation symbol sequences at a speed faster than a Nyquist rate.
