Abstract
A decoding apparatus is provided. The decoding apparatus includes a communication unit for receiving multiple encoding data respectively corresponding to multiple areas constituting one image, and reference data including attribute information of each of the multiple areas, and a processor for generating multiple divided images by decoding the multiple encoding data respectively, changing the resolutions of some divided images among the multiple divided images on the basis of the received attribute information, and generating a reconstructed image by merging the some divided images having the changed resolutions and the remaining divided images.
Claims13
A decoding apparatus, comprising:
- a communication interface configured to:
- receive a plurality of encoding data respectively corresponding to a plurality of areas constituting an image,
- receive reference data including attribute information of each of the plurality of areas, and
- receive filter information;
- and
- a processor configured to:
- generate a plurality of divided images from the image by decoding the plurality of encoding data,
- determine whether to change resolutions of at least one divided image among the plurality of divided images based on the attribute information,
- change resolutions of the at least one divided image based on the determination result, and
- generate a reconstructed image by applying a filter corresponding to the filter information to the at least one divided image having the changed resolutions and merging the at least one divided image to which the filter is applied with remaining divided images.
A method for controlling a decoding apparatus, the method comprising:
- receiving a plurality of encoding data respectively corresponding to a plurality of areas constituting one image;
- receiving reference data including attribute information of each of the plurality of areas;
- receiving filter information;
- generating a plurality of divided images by decoding the plurality of encoding data;
- determining whether to change resolutions of at least one divided image among the plurality of divided images based on the received attribute information;
- changing resolutions of the at least one divided image based on the determination result;
- and
- generating a reconstructed image by applying a filter corresponding to the filter information to the at least one divided image having the changed resolutions and merging the at least one divided image to which the filter is applied with remaining divided images.
