Abstract:
PURPOSE: A video encoding method for performing prediction between inter-layers with preprocessing filtering and a device thereof, a video decoding method for performing the prediction between the inter-layers with postprocessing filtering and the device thereof are provided to perform the preprocessing filtering or the postprocessing filtering considering correlation between a basic inter-layer and an improved inter-layer when video of composite image is encode/decoded based on the prediction between the basic inter-layer and the improved inter-layer. CONSTITUTION: An inter-layer component classifying unit(110) classifies an inputted image with a first component and a second component by using sampling. A basic inter-layer encoding unit(120) encodes the first component of the image and generates a basic inter-layer bit stream. A preprocessing filtering unit(130) performs preprocessing filtering for improving correlation the first component about the second component of the image. An improved inter-layer encoding unit(140) generates an improved inter-layer bit stream by encoding the second component based on the first component.

Abstract:
PURPOSE: An encoding method of a multiview video, an apparatus thereof, a decoding method and an apparatus thereof are provided to supply a skip mode in a multiview video coding and to increase the compression efficiency of an image. CONSTITUTION: A motion prediction unit generates a skip motion vector in the vision direction of a current block(710). A motion compressing unit compresses motion about the current block from a frame of a second point based on the skip motion vector(720). An entropy encoding unit encodes mode information about the skip motion vector(740).
