Disclosed is a method of generating a volume hologram using a point cloud and a mesh, in which a weight is given to a brightness of a light source according to a direction of a light in order to record a hologram of better quality. The method includes: (a) acquiring multi-view depth and color images; (b) generating point cloud data of a three-dimensional object from the acquired multi-view depth and color images; (c) generating mesh data of the three-dimensional object from the point cloud data of the three-dimensional object; (d) calculating a normal vector of each mesh from the mesh data of the three-dimensional object; (e) extracting three-dimensional data at a user viewpoint from the mesh data of the three-dimensional object by using the normal vector of the mesh; and (f) generating hologram data from three-dimensional data at the user viewpoint.

Method of generating volume hologram using point cloud and mesh

Disclosed is a skeleton-based dynamic point cloud estimation system for sequence compression, capable of generating a three-dimensional skeleton and a motion vector thereof from a group of point cloud frames to estimate a point cloud of a next frame, and compressing a point cloud sequence by obtaining a residual between the estimated point cloud and an original point cloud. Since the point cloud is estimated by using the motion vector of the skeleton, and the sequence is compressed by using a difference from an original value as the residual, an amount of point clouds to be input to a compressor is significantly reduced, so that compression efficiency is improved.

Skeleton-based dynamic point cloud estimation system for sequence compression

A blockchain data recording method includes determining a recording type as one of an on-chain type and an off-chain type according to a target data to be recorded in a blockchain, transmitting a first transaction proposal for recording the target data in a blockchain node configured to store an on-chain data on a blockchain to the blockchain node when the recording type is an on-chain type, and recording the target data in a storage node provided to store an off-chain data, and transmitting a second transaction proposal for storing recording information of the target data in the blockchain to the blockchain node when the recording type is an off-chain type.

Blockchain data recording method and apparatus thereof

A data management system according to an embodiment of this invention includes a blockchain node configured to store on-chain data on blockchain and a service server, upon receiving a service request associated with the original data from a client, i) accessing off-chain data stored in a storage node or recording off-chain data in the storage node according to the service request, and ii) sending a transaction proposal to the blockchain node for a record associated with the service request to be stored in the blockchain.

Blockchain based data management system and method thereof

A digital identity management method based on a blockchain-based technology is provided. In some exemplary embodiments, the method comprises: performing a first process for storing identity identification information of a subscription request in a first block of a blockchain in response to the subscription request from a service request device and then obtaining a block hash value of the first block as a result of performing the first process, performing a second process for storing the block hash value of the first block and data of authentication information of the subscription request in a second block of the blockchain and then obtaining a block hash value of the second block as a result of performing the second process, and inserting the block hash value of the second block into a digital identity data structure as a result of processing the subscription request.

Blockchain-based digital identity management method

A blockchain-based method is described which is related to transferring electronic currency from a payer to a payee. In some embodiments, a first process, a second process and a third process are performed. The first process includes receiving a processing request for a target transaction from a terminal of a payer, and transferring the processing request to a first blockchain node among a plurality of blockchain nodes. When a verification result indicates that the target transaction is valid, the method proceeds to performing the second and third processes. The second process includes transferring electronic currency from an electronic wallet of the payer to an electronic wallet of the payee. The third process includes recording data for the target transaction in a new block, and spreading the new block over the blockchain network. In some embodiments, the second process and the third process are performed in parallel.
