Abstract: An apparatus and method for adaptive layer selection and a server having the same are provided. The adaptive layer selecting apparatus includes a monitoring unit monitoring a connection state of at least one channel connected through a communication network, a channel managing unit detecting available channels to be used for providing a service based on a result of the monitoring, and a layer managing unit determining the number of adaptive layers to be used for encoding based on bandwidths of changed available channels when the number of the available channels is changed.

Abstract: Disclosed are a method and an apparatus for determining displacement information of a target area by using information that is present in an image frame. The method of determining displacement information according to an embodiment of the present disclosure may include: setting a target area in which an object that displacement information determination thereof is required is positioned within a target frame; determining a tracking area in a tracking frame based on displacement information of at least one neighboring target area that is positioned around the target area; and determining a matching area that matches with the target area in the tracking area and determining the displacement information of the target area.

Abstract: A method for load balancing in a base station is provided. The base station updates a traffic amount of a current time by reflecting a predicted traffic amount of a future time in the traffic amount of the current time, and determines parameters necessary for load balancing of the base station by comparing the updated traffic amount of the current time with a predetermined threshold.

Abstract: Disclosed are a method of upsampling based on a maximum-resolution image and red, green and blue (RGB) composition and an apparatus performing the same. An image generating method may include acquiring visible-channel images included in multi-spectrum images, upsampling a remaining image excluding a maximum-resolution image from the visible-channel images, based on the maximum-resolution image among the visible-channel images, and generating an RGB composite image by composing the upsampled remaining image and the maximum-resolution image.
