Method and apparatus for encoding of video using depth information
Provided is a method for encoding an image using a depth information that includes selecting a current coding unit (CU); verifying an object information of the current CU from an object information obtained from a depth image; and verifying whether or not the current CU is composed of a single object based on the object information, and predicting a division structure of the current CU according to whether or not the current CU is composed of a single object.
1. A method for encoding an image using a depth information, the method comprising:
selecting a current coding unit (CU);
verifying an object information of the current CU from an object information obtained from a depth image; and
verifying whether or not the current CU is composed of a single object based on the object information, and predicting a division structure of the current CU according to whether or not the current CU is composed of a single object,
wherein predicting the division structure of the current CU comprises a process that decides not to divide the current CU and ends a division structure prediction when the current CU and a peripheral CU of the current CU are each composed of a single object and are included in the same object.
2. The method according to claim 1 , wherein predicting the division structure of the current CU comprises a process that decides not to divide the current CU when the current CU has a size less than a predetermined value and is composed of a single object.
3. A method for encoding an image using a depth information, the method comprising:
selecting a current coding unit (CU);
verifying an object information of the current CU from an object information obtained from a depth image; and
verifying whether or not the current CU is composed of a single object based on the object information, and predicting a division structure of the current CU according to whether or not the current CU is composed of a single object,
wherein predicting the division structure of the current CU comprises a process that decides not to divide the current CU and ends a division structure prediction when the current CU and a peripheral CU of the current CU are each composed of a single object and are included in the same object, and a size of the peripheral CU is equal to or greater than a predetermined value.
4. An apparatus for encoding an image using a depth information, the apparatus comprising:
an object information verifying portion that verifies an object information of a current coding unit (CU) from an object information obtained from a depth image; and
a division structure prediction portion that verifies whether or not the current CU is composed of a single object based on the object information, and predicts a division structure of the current CU according to whether or not the current CU is composed of a single object,
wherein the division structure prediction portion decides not to divide the current CU and ends a division structure prediction when the current CU and a peripheral CU of the current CU are each composed of a single object and are included in the same object.
5. The apparatus according to claim 4 , wherein the division structure prediction portion decides not to divide the current CU when the current CU has a size less than a predetermined value and is composed of a single object.
6. An apparatus for encoding an image using a depth information, the apparatus comprising:
an object information verifying portion that verifies an object information of a current coding unit (CU) from an object information obtained from a depth image; and
a division structure prediction portion that verifies whether or not the current CU is composed of a single object based on the object information, and predicts a division structure of the current CU according to whether or not the current CU is composed of a single object,
wherein the division structure prediction portion decides not to divide the current CU and ends a division structure prediction when the current CU and a peripheral CU of the current CU are each composed of a single object and are included in the same object, and a size of the peripheral CU is equal to or greater than a predetermined value.
