Abstract: Disclosed herein is an apparatus and method for providing additional information to an FU in a reconfigurable codec. The apparatus includes a syntax parser, a prediction mode converter unit, and an inverse prediction unit. The syntax parser parses the encoding type value of a multimedia bit stream and a first prediction mode value from the multimedia bit stream. The prediction mode converter unit converts the first prediction mode value into a second prediction mode value corresponding to the encoding type value. The inverse prediction unit determines an inverse prediction operating mode based on the second prediction mode value.

Abstract: Disclosed herein is an apparatus and method for estimating the joint structure of a human body. The apparatus includes a multi-view image acquisition unit for receiving multi-view images acquired by capturing a human body. A human body foreground separation unit extracts a foreground region corresponding to the human body from the acquired multi-view images. A human body shape restoration unit restores voxels indicating geometric space occupation information of the human body using the foreground region corresponding to the human body, thus generating voxel-based three-dimensional (3D) shape information of the human body. A skeleton information extraction unit generates 3D skeleton information from the generated voxel-based 3D shape information of the human body. A skeletal structure estimation unit estimates positions of respective joints from a skeletal structure of the human body using both the generated 3D skeleton information and anthropometric information.

Abstract: Disclosed herein are an apparatus and method for reconstructing a three-dimensional (3D) face based on multiple cameras. The apparatus includes a multi-image analysis unit, a texture image separation unit, a reconstruction image automatic synchronization unit, a 3D appearance reconstruction unit, and a texture processing unit. The multi-image analysis unit determines the resolution information of images received from a plurality of cameras, and determines whether the images have been synchronized with each other. The texture image separation unit separates a texture processing image by comparing the resolutions of the received images. The reconstruction image automatic synchronization unit synchronizes images that are determined to be asynchronous images by the multi-image analysis unit. The 3D appearance reconstruction unit computes the 3D coordinate values of the synchronized images, and reconstructs a 3D appearance image. The texture processing unit reconstructs a 3D image by mapping the texture processing image to the 3D appearance image.
