20100156901METHOD AND APPARATUS FOR RECONSTRUCTING 3D MODEL - A method of reconstructing a 3D model includes reconstructing a 3D voxel-based visual hull model using input images of an object captured by a multi view camera; converting the 3D voxel-based visual hull model into a mesh model; and generating a result of view-dependent rendering of a 3D model by performing the view-dependent texture mapping on the mesh model obtained through the conversion. Further, the reconstructing includes defining a 3D voxel space to be reconstructed; and excluding voxels not belonging to the object from the defined 3D voxel space.06-24-2010
20100156935METHOD AND APPARATUS FOR DEFORMING SHAPE OF THREE DIMENSIONAL HUMAN BODY MODEL - A method of deforming a shape of a human body model includes the steps of reorganizing human body model data into a joint-skeleton structure-based Non-Uniform Rational B-spline (NURBS) surface model, generating statistical deformation information about control parameters of the NURBS surface model based on parameters of joints and key section curves for specific motions, and deforming the shape of the human body model based on the NURBS surface model and the statistical deformation information. The human body model data includes three-dimensional (3D) human body scan data and a 3D polygon mesh.06-24-2010
20100157020MULTIPLE CAMERA CONTROLLING AND IMAGE STORING APPARATUS FOR SYNCHRONIZED MULTIPLE IMAGE ACQUISITION AND METHOD THEREOF - The invention provides a camera controlling and image storing apparatus for synchronized multiple image acquisition and method thereof, which cut down equipment costs by taking a software approach with respect to various demands of viewers for a broadcasting image. A camera controlling and image storing apparatus, the apparatus includes an image acquiring unit for acquiring synchronized images from multiple cameras losslessly, one or more ingest agents for storing the acquired images, and controlling pan, tilt and zoom operations of the cameras based on the acquired images, and a central server for transmitting a control command to the ingest agents, and receiving and integrating collectively the stored images of the ingets agent.06-24-2010
20100157022METHOD AND APPARATUS FOR IMPLEMENTING MOTION CONTROL CAMERA EFFECT BASED ON SYNCHRONIZED MULTI-IMAGES - A method of implementing a motion control camera effect includes: inputting images of an object captured at one or more points of view; inputting a control parameter containing a motion control camera effect to be applied to the input images, a target time of the motion control camera effect, and a reproducing speed; extracting frames of the target time from the input images; processing the frames using software based on the control parameter; and outputting the processed frames at the reproducing speed. The motion control camera effect includes at least one of a motion control camera effect for a fixed viewpoint still object, a motion control camera effect for a fixed viewpoint moving object, a motion control camera effect for a free viewpoint still object, a motion control camera effect for a free viewpoint moving object, and a dual motion control camera effect.06-24-2010
20100158354METHOD OF CREATING ANIMATABLE DIGITAL CLONE FROM MULTI-VIEW IMAGES - The present invention relates to a method of creating an animatable digital clone includes receiving input multi-view images of an actor captured by at least two cameras and reconstructing a three-dimensional appearance therefrom, accepting shape information selectively based on a probability of photo-consistency in the input multi-view images obtained from the reconstruction and transferring a mesh topology of a reference human body model onto a shape of the actor obtained from the reconstruction. The method further includes generating an initial human body model of the actor via transfer of the mesh topology utilizing sectional shape information of the actor's joints, and generating a genuine human body model of the actor from learning genuine behavioral characteristics of the actor by applying the initial human body model to multi-view posture learning images where performance of a predefined motion by the actor is recorded.06-24-2010
