Abstract: Provided are an apparatus and method for cleaning up footskate in real-time character animation that is generated using a depth camera. According to an aspect, a character image processing apparatus determines, when a character image frame is received, whether a character's foot included in the character image frame reaches a predetermined ground; sets a first character image frame in which a character's foot reaches the predetermined ground as a reference constraint frame; and designates the character's foot position in the reference constraint frame as a reference foot position. Then, the character image processing apparatus extracts any constraint frames in which the character's foot has to reach the predetermined ground from among character image frames received sequentially following the reference constraint frame, and adjusts a posture of the character in each constraint frame based on the reference foot position.

Abstract: Disclosed herein are a location tracking apparatus and method. The location tracking apparatus includes a head tracking unit, and a pointer tracking unit. The head tracking unit extracts a location, 3DOF and orientation of a head of a user by capturing the user from a screen on which a game is displayed using a first webcam and tracks the user's gaze based on the results of the extraction. The pointer tracking unit tracks a point indicated by a laser pointer projected onto the screen by capturing the screen using a second webcam, and designates the tracked point as cross hairs corresponding to a target to be shot at. The head tracking unit and the pointer tracking unit tracks the user's gaze and the point simultaneously.

Abstract: A method of producing a locomotion animation includes calculating movement information of the objects on the basis of surrounding information of the objects and motion capture data for the subjects, and measuring a collision between the objects or between an object and an obstacle on the basis of the movement information to calculate riding motion information for the subjects. The movement information and the riding motion information are then synthesized to determine movement motion and riding animations of the objects. Therefore, the motions of locomotion can be naturally connected with each other.

Abstract: Disclosed herein is a method and apparatus for generating graphic tentacle motions. In the method, a 3D tentacle is divided into a 1D center line and a 2D surface based on information about an initial mesh of the 3D tentacle. New locations of sample points of the center line in a new frame are determined from initial locations of sample points of the center line, based on a tentacle root motion. New locations of sample points of the surface in the new frame are determined from initial locations of sample points of the surface, based on both the initial locations of the center line sample points and the tentacle root motion. The surface is coupled to the center line using the locations of the sample points of both the center line and the surface in the new frame.

Abstract: Provided is an apparatus for targeted advertising based on images of passersby. A passerby image extraction unit extracts an image of a passerby. A trait information extraction unit extracts trait information regarding the passerby from the extracted image. A targeted advertisement obtainment unit obtains a targeted advertisement to be displayed based on the trait information. A targeted advertisement display unit displays the targeted advertisement.

Abstract: An apparatus for detecting a pose in motion capture data includes: a motion data input unit which receives motion data of characters; a virtual marker attaching unit for forming a point cloud by attaching virtual markers to joints of an end-effector of each character; and a scaling unit for, when a frame has different character size from an a character size of an original frame to be compared is detected, scaling the character size. The apparatus further includes an ICP algorithm execution unit for finding a matching transformation matrix between the original frame and each frame of the motion data, of which character size has been scaled, by applying an ICP algorithm, and determining a frame, in which character's pose has the smallest difference from that in the original frame based on a sum of the distances between the virtual markers chosen by sampling the matched two poses.

The apparatus further includes a robot motion control unit for controlling a robot by inputting preset torque values to related joint motors of the robot by referring to the dynamics motion data.
