An image processing apparatus. The image processing apparatus may perform filtering to emphasize a surface lighting of a low frequency band from an input lighting environment image, and may also perform at least one virtual point light (VPL) sampling from the input lighting environment image. The image processing apparatus may perform precomputed radiance transfer (PRT) based rendering using the filtered lighting environment image and VPL based rendering using the sampled VPL.

An image processor, a lighting processor, and a method therefore are provided. According to one aspect of the invention, the lighting processor can extract information related to defuse lighting applied to a real object using a colored image and a depth image of the real object. The lighting processor can recover the diffuse image for the real object using the extracted information related to diffuse lighting, and generate either a speculum image or a shadow image using the recovered diffuse image and the colored image.

Provided is a method and apparatus for realistically reproducing an eyeball that may verify and analyze a material property and a deformation property with respect to each of constituent portions of an eyeball and may render each of the constituent portions based on the analyzed priorities, thereby more realistically reproducing the eyeball.
摘要:
A data processing apparatus and method. A vertex grouping unit of the data processing apparatus may group, into at least one group, a plurality of vertices included in a three-dimensional (3D) object desired to be compressed. A prediction mode determination unit may determine a prediction mode for compressing a vertex position with respect to each of the at least one group. A coder may code a prediction error vector and an identification (ID) index of the prediction mode determined with respect to each of the at least one group.
摘要:
A marker-less augmented reality system that may extract a plurality of planes included in an image generated by a camera, based on three-dimensional (3D) information of the image, and may estimating a pose of the camera based on a correspondence among the plurality of planes extracted, and an operating method thereof.

Disclosed is a method and apparatus for encoding a three-dimensional (3D) mesh. The method for encoding the 3D mesh includes determining a priority of a gate configuring a 3D mesh corresponding to a 3D object, removing vertices configuring the 3D mesh using the determined priority of the gate, and simplifying the 3D mesh.
