Abstract: Disclosed herein are an apparatus and method for compressing 3D volume data. The apparatus for compressing three-dimensional (3D) volume data includes one or more processor, and execution memory configured to store at least one program that is executed by the one or more processors, wherein the at least one program is configured to receive 3D volume data for data compression, select necessary voxels that contribute to formation of a geometric surface from the 3D volume data using a marching cubes algorithm, represent location information of the selected necessary voxels by a tree structure, and binarize the location information of the necessary voxels by serializing the tree structure, and quantize truncated signed distance values to surfaces adjacent to the necessary voxels constituting a volume from the 3D volume data using the binarized location information of the necessary voxels.

Abstract: Disclosed herein are an image compression apparatus and method. The image conversion method includes generating a multi-plane image reconfigured into layers in a depth direction based on multiple pieces of multi-view image data, generating an aggregated layer by aggregating the layers of the multi-plane image into at least one layer, and converting a multi-plane image including the aggregated layer into a two-dimensional (2D) atlas image.

Abstract: Disclosed herein is a method for operating an apparatus for generating an all-in-focus image. The method may include generating a focus-map-calculating model through deep learning for images having different focuses and a reference all-in-focus image corresponding thereto, calculating a focus map for each of multi-focus images, which are captured by a camera, using the focus-map-calculating model, and generating an all-in-focus image for the multi-focus images using the focus map.

Abstract: Disclosed is a technology for providing a content on the basis of DASH adaptive to a variable bandwidth. The present invention may comprise: a bandwidth measurement unit for measuring a bandwidth of a network connected to a terminal at predetermined time intervals; a segment generation unit for generating a plurality of segments, wherein the plurality of segments have a predetermined bitrate difference therebetween; and a media information generation unit for generating a media presentation description which includes information on the representation including the plurality of generated segments, wherein the segment generation unit calculates segment lengths using arithmetic operations on the predetermined time interval and the probability that an ith bandwidth itself among bandwidths of the network measured at the predetermined time intervals is increased or decreased by half of the predetermined bitrate difference, and generates a plurality of segments corresponding to the calculated lengths.
