Method for decoding images based upon partition information determinations and apparatus for decoding using same
The present invention relates to image encoding and image decoding. A method for encoding images according to the present invention comprises the steps of: acquiring division information from peripheral blocks of an encoding target block with respect to the peripheral blocks; predicting the division of the encoding target block on the basis of the acquired division information; encoding information on the difference between the practical division information of the encoding target information and the predictive division information predicted in the predicting process; and transmitting the encoded information. The present invention can encode/decode the division information of the encoding/decoding target blocks using the information about the peripheral blocks.
1. A method for decoding image, the method comprising:
receiving coding information;
determining if predication partition information has been used and if prediction partition information has been used:
obtaining at least one of information about neighboring blocks of a target decoding block;
predicting partition information of the target decoding block based on the obtained information about the neighboring blocks;
determining if partition information equals the prediction partition information; and
if the partition information equals the prediction partition information, using the prediction partition information as partition information of the target decoding block and restoring partition information of the target decoding block.
2. The method of claim 1 ,
wherein the obtained information about the neighboring blocks comprises at least one of dissimilarity in intra prediction direction information about the neighboring blocks, dissimilarity in motion information about the neighboring blocks, dissimilarity in filter information about the neighboring blocks, dissimilarity in transform information about the neighboring blocks, size information about the neighboring blocks, gradient information of pixel values about the neighboring blocks, and partition information of the neighboring blocks.
3. The method of claim 1 ,
wherein if the partition information does not equal the prediction partition information, decoding information about the partition of the target decoding block and restoring partition information of the target decoding block.
4. The method of claim 1 , wherein if a determination is made that prediction partition information has not been used, information about the partition of the target decoding block is decoded and partition information of the target decoding block is restored.
