METHOD AND DEVICE FOR ENCODING DEPTH IMAGE

摘要

PURPOSE: A 3-dimensional image encoding method and a device thereof are provided to improve the coding efficiency by an efficient configuration of filters for 3-dimensional image, and an efficient intra-prediction method suitable for 3-dimensional image. CONSTITUTION: A de-blocking filter of a filter unit (180) removes a blocking phenomenon. A filter classification unit (210) of the filter unit classifies the filtering method by calculating the cost for weighted sum screen of the screen passed through the de-blocking filter and the screen not passed through the de-blocking filter, and the cost for the screen passed through the de-blocking filter. Multiple classification filters (220-226) of the filter unit performs a filtering according to the classified filtering method.
