An apparatus and method of correcting an image are provided. The apparatus includes a receiver to receive a depth value and a luminous intensity, the depth value and the luminous intensity being measured by at least one depth sensor, and a correction unit to read a correction depth value of a plurality of correction depth values mapped to different depth values and different luminous intensities from a first storage unit and to correct the measured depth value using the read correction depth value, the correction depth value being mapped to the measured depth value and the measured luminous intensity.

Provided are a display device and a non-transitory computer-readable recording medium. By comparing a priority of an animation clip corresponding to a predetermined part of an avatar of a virtual world with a priority of motion data and by determining data corresponding to the predetermined part of the avatar, a motion of the avatar in which motion data sensing a motion of a user of a real world is associated with the animation clip may be generated.

A method, medium and apparatus determining whether models collide with each other. In the model collision detecting method, medium and apparatus, it is possible to quickly examine whether models collide, and to recognize the collision generated at an arbitrary time, which is not a predetermined collision check time of the models, without missing the recognition of the collision generated at the arbitrary time, by determining whether paths reflecting movement of the model primitives between the current time and a previous time overlap when the model primitives do not collide at the current time, determining whether the model primitives collide with each other at an arbitrary time between the current time and the previous time when the path primitives overlap each other, and recognizing that the models collide with each other at the arbitrary time when the model primitives collide with each other at the arbitrary time.

A graphic data encoding method and apparatus generating a bitstream by encoding a header having at least one piece of first information determined in consideration of a predetermined graphic profile from among multiple pieces of encodable first information; and encoding a payload having at least one piece of second information determined in consideration of the predetermined graphic profile from among multiple pieces of encodable second information. A graphic data decoding method and apparatus decode the generated bitstream. Irrespective of the functions that can be performed by the graphic data encoding apparatus and the functions that can be performed by the graphic data decoding apparatus, the graphic data decoding apparatus, which is in accordance with a graphic profile, can completely restore a 3D mesh model described in the bitstream generated by the graphic data encoding apparatus that is satisfactory to the graphic profile.

Disclosed is a three-dimensional (3D) mesh compression apparatus and method. The 3D mesh compression apparatus may generate a base mesh through a mesh simplification, may separately compress the base mesh and peaks eliminated by the simplification, may construct a covariance matrix based on a topological distance between the eliminated peaks, and may compress 3D mesh data based on the covariance matrix.

A 3D graphics processing method, medium and apparatus performing perspective correction is described. The 3D graphics processing method includes receiving a homogeneous coordinate and an attribute value of both end points of one scan line of a polygon composed of a plurality of perspective projected vertices, calculating a reference value indicating an amount of perspective distortion in the scan line using the received homogeneous coordinates, and interpolating an attribute value of each of pixels of the scan line using at least some of the received homogeneous coordinates and attribute values, the attribute value interpolated by selectively applying perspective correction to each pixel based on the reference value. Accordingly, processing time and power consumption may be reduced.
