Abstract:
A method for tracking an object in an object tracking apparatus includes receiving an image frame of an image; and detecting a target, a depth analogous obstacle and an appearance analogous obstacle; tracking the target, the depth analogous obstacle and the appearance analogous obstacle; when the detected target overlaps the depth analogous obstacle, comparing the variation of tracking score of the target with that of the depth analogous obstacle. Further, the method includes continuously tracking the target when the variation of tracking score of the target is below that of the depth analogous obstacle and processing a next frame when the variation of tracking score of the target is above that of the depth analogous obstacle; and re-detecting the target.

An apparatus for creating a radio map includes a radio signal acquiring unit that acquires information on radio signals between one or more cooperative intelligent robots, a radio environment modeling unit that estimates radio strength for each cell configuring the radio map from the information on radio signals acquired by the radio signal acquiring unit, and a radio map creating unit that classifies a communication region of each cell and models the radio map according to the radio strength for each cell estimated by the radio environment modeling unit.
Abstract:
Provided are a method for determining a moving direction of a terminal and correcting a position thereof, and a positioning apparatus using the same. Relative direction information is estimated based on N pieces of position information of the terminal, and distortion information is removed from the relative direction information to acquire relative direction information without direction integrity. Further, the relative direction information is transmitted into absolute direction information to acquire a moving path direction of the terminal. Next, the position information of the terminal is corrected based on the moving path direction of the terminal.

An apparatus and method for loading a radiomap database (DB) and a terminal device are disclosed. The apparatus for loading a radiomap DB includes a moving information calculation unit, and a loading performance unit. The moving information calculation unit calculates the moving information of a terminal based on the difference between a previous location and estimated final location of the terminal as the terminal moves. The loading performance unit loads a radiomap DB, including information about a neighboring node of each reference point, and a radiomap DB, including information about a neighboring node of a reference point, located in a direction in which the terminal moves, based on the moving information calculated by the moving information calculation unit.

Disclosed are a method and an apparatus for predicting human motion in a virtual environment. The apparatus includes a motion tracking module configured to estimate a human pose of a current time step based on at least one piece of sensor data and a pre-learned motion model, and a motion model module configured to predict a set of probable human poses in the next time step based on the motion model, the estimated human pose of the current time step, and virtual environment context information of the next time step. A sense of immersion of the virtual environment may be maximized.
Abstract:
Disclosed herein is an apparatus and method for calculating a TCP checksum. An apparatus for calculating a TCP checksum includes a data division unit for dividing content to be transmitted into two or more primary data fragments by a unit of a preset byte. A first checksum calculation unit calculates first checksums for the primary data fragments, respectively. A second checksum calculation unit calculates a second checksum for secondary data to be inserted into a data area of the TCP segment using the first checksums. Accordingly, in TCP-based networks, a checksum calculation procedure is improved upon transmitting static content, so that a static content transfer rate occupying most of TCP-based network traffic can be improved.
