    摘要: A method and apparatus for enhancing quality of a depth image are provided. A method for enhancing quality of a depth image includes: receiving a multi-view image including a left image, a right image, and a center image; receiving a current depth image frame and a previous depth image frame of the current depth image frame; setting an intensity difference value corresponding to a specific disparity value of the current depth image frame by using the current depth image frame and the previous depth image frame; setting a disparity value range including the specific disparity value; and setting an intensity difference value corresponding to the disparity value range of the current depth image frame by using the multi-viewpoint image.

    摘要: Provided are an apparatus and method for predictive coding/decoding for improving a compression rate of multiview video using one or two additional reference frame buffers. The predictive encoding apparatus includes: a multiview reference picture providing unit for providing a reference picture for a predictive encoding according to temporal and spatial GOP structure information; a prediction unit for creating a vector by predicting which part of the reference picture inputted from the multiview reference picture providing unit is referred by a picture to currently encode; a transforming and quantizing unit for obtaining a difference signal between the predicted signal inputted from the prediction unit and a picture signal to currently encode, transforming the obtained difference signal, quantizing the transformed signal, and compressing the quantized signal; and an entropy encoding unit for encoding the quantized signal and the vectors according to a predetermined scheme and outputting the encoded signal.

    摘要: Provided is a five sensory data synchronizing and transmitting apparatus and method, and an actual-feeling multimedia data providing system and method using the same. The five sensory data synchronizing and transmitting apparatus and method forms packets by describing vibration, an odor and a taste expressed in video/audio based on touch, odor and taste data descriptors and synchronizes the touch/odor/taste packets with video/audio packets on a frame basis; and then, the actual-feeling multimedia data providing system and method demultiplexes the received packets transmitted from the five sensory data synchronizing and transmitting apparatus into video data, audio data, touch data, odor data and taste data and transmits them to corresponding devices to thereby provide a user with an actual-feeling multimedia service.
