METHOD AND APPARATUS FOR DECODING VIDEO IMAGE

摘要

According to the embodiment of the present invention, a method for decoding a video image comprises: a step for receiving a fraction of the information for original image data, a step for generating plural kinds of side information by predicting the original image data, a step for generating the final side information by applying a fraction of the information to each kind of side information, and a step for decoding the original image data using a fraction of the information and the final side information. When the original image data is decoded in a decoder, the data with the minimum errors compared with the original image data can be selected from the plural kinds of information generated by the decoder so that the decoded image quality may be improved. The compression performance for distributed video coding can be improved as a result of excluding the transmission of additional information for confirming the accuracy of the data that decoded the original image.
