DEVICE AND A METHOD OF DECODING A DISPERSION VIDEO ENCODING IMAGE, CAPABLE OF IMPROVING THE COMPRESSION PERFORMANCE BASED ON MULTIPLE NOISE MODEL

摘要

PURPOSE: A device and a method of decoding a dispersion video encoding image are provided to effectively remove noise error of assistance information as minimizing the waste of compression data, thereby remarkably increasing the compression performance.;CONSTITUTION: A key feature restoring unit restores key feature information transmitted from a decoding device(20). An assistance information generating unit(22) generates assistance information by using the key feature restored in the key feature restoring unit. A multi noise model based noise model providing unit provides noise model to be use in a certain channel coding unit. A channel code decoding unit decodes certain channel coding units about a given decoding unit.;COPYRIGHT KIPO 2011
