Abstract: A video decoding method comprises warping different viewpoint images into a virtual viewpoint by using depth information of an input viewpoint; determining a first weight for the pixels based on quality and depth of pixels of the warped viewpoint images; determining a second weight for the pixels based on a location relation between the pixels of the warped viewpoint images and the virtual viewpoint; determining a blending weight for the pixels based on the first weight and the second weight; blending the warped viewpoint images according to the blending weight; and synthesizing an image of the virtual viewpoint based on the blended viewpoint images.

Abstract: A Faster-Than-Nyquist (FTN) signal transmission apparatus and method thereof. The signal transmission apparatus includes a pilot interference estimator and compensator configured to estimate interference on pilot symbols by a Faster-Than-Nyquist (FTN) signal generated by FTN modulating a sequence of data symbols, and generate a compensated pilot symbol sequence to cancel the estimated interference; a pilot FTN modulator configured to generate an FTN pilot signal in which inter-pilot symbol interference does not occur, by performing FTN pulse-shaping on the compensated pilot symbol sequence; and a transmitter configured to transmit an FTN data signal and the FTN pilot signal.

Abstract: The present disclosure provides an apparatus and a method for selecting camera providing input images to synthesize virtual view images. According to the present disclosure, A method of selecting a camera providing as input image to synthesize a virtual view image, the method may comprise, for a camera providing an input image, determining whether or not the camera is comprised in a field of view (FoV) at a virtual view position and in response to the camera determined to be comprised in the field of view, selecting the camera to synthesize the virtual image, wherein the determining determines, by way of comparison, whether or not a direction from the virtual view position to a position of the camera is in the FoV at the virtual view position.
