Abstract: A method of managing a network bandwidth by controlling of an image compression rate and controlling of a frame generation, and an image transmission system using the same are provided. The method includes approving generation of an intra-frame (I-frame) for one among a plurality of image compression hardware (H/W) units, storing compressed image data compressed by the plurality of image compression H/W units in a plurality of buffers corresponding to the plurality of image compression H/W units, controlling a data storage level of the plurality of buffers, and encapsulating the compressed image data stored in each of the plurality of buffers into a network packet and transmitting the encapsulated image data to the outside through an external network.

Abstract: Provided is a method of removing noise from a sparse depth map. The method includes setting, as nodes, sample points in a sparse depth map including depth information at a certain position of an image plane, constructing a mesh by connecting the set nodes, and removing noise from the meshed node, based on connection information between the meshed node and neighboring nodes adjacent thereto and color information about a color image corresponding to the sparse depth map. A depth value is allocated to each of the sample points.
