Abstract: An arbitrary viewpoint image generation method includes obtaining an original image set photographed by a plurality of cameras included in a camera array at each of at least one focal distance at a same time point; obtaining a multi-focus image set by generating a multi-focus image from the original image set for each of the at least one focal distance; and generating an arbitrary viewpoint image at a position where a viewpoint is to be moved from the multi-focus image set.

Abstract: Disclosed is an apparatus and method of segmenting an object. An object segmentation method according to the present disclosure includes: receiving an input image; receiving a user input indicating at least one piece of information on a foreground region and a background region included in the input image; generating at least one among a foreground pixel list and a background pixel list using the received user input; calculating Gaussian distribution of at least one pixel that makes up the input image using at least one among the generated foreground pixel list and background pixel list; and determining whether the at least one pixel is a foreground pixel or a background pixel using the calculated Gaussian distribution.

Abstract: Provided are three-dimensional (3D) data processing apparatus and method. 3D stereoscopic image common format data preserving common 3D image information is defined by converting 3D stereoscopic image data of each format to apply the same 3D image processing algorithm to 3D data of various formats, and native format data of each format is maintained to maintain merits of each format, and a format-specific algorithm table is maintained with respect to a common 3D image processing function, whereby the same 3D image processing algorithm may be applied to various 3D data and a unique algorithm allowing for maintaining the merits of each 3D data may be applied.
