Abstract: A method for tracking multiple image objects, includes resampling particles from each of the image objects tracked in a previous image, calculating respective weights of the resampled particles, and predicting and tracking locations of the image objects in a current image based on values obtained by multiplying the locations of the particles by corresponding weights, wherein when an image object of the previous image has a neighboring image object located within a threshold distance, weights of the particles sampled from the image object are calculated by multiplying image values of the current image by penalties, which are values of distances between the corresponding particles and the neighboring image object. The method is capable of avoiding a hijacking problem in which identifiers of nearby objects are confused with each other or disappear during the tracking of multiple objects.

Abstract: The present description relates to a BAN (Body Area Network) wireless communication control method, and more particularly, to a BAN wireless communication control method to which a selective discovery technique is applied. The present invention provides a BAN wireless communication control method, comprising the steps of transmitting a discovery request frame including a selective standard profile, and receiving a discovery response frame from a host that provides at least one of services specified in the selective standard profile.

Abstract: The present description relates to a cache based ZigBee network discovery method. A first service profile that specifies a service selected by a user is generated, and it is determined whether previously stored ZigBee network related information includes information about a service providing network that provides the service specified by the first service profile. A first network discovery procedure is performed when it is determined that the previously stored ZigBee network related information does not include the information about the service providing network, and a second network discovery procedure is carried out when it is determined that the previously stored ZigBee network related information includes at least one piece of information about the service providing network.

Abstract: A moving robot and moving object detecting method and medium thereof is disclosed. The moving object detecting method includes transforming an omni-directional image captured in the moving robot to a panoramic image, comparing the panoramic image with a previous panoramic image and estimating a movement region of the moving object based on the comparison, and recognizing that a movement of the moving object exist in the estimated movement region when the area of the estimated movement region exceeds the reference area.
