Abstract
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.
Claims10
A method for encoding an image using a depth information, the method comprising:
- selecting a current coding unit (CU);
- judging whether or not the current CU is composed of a single object when a size of the current CU is equal to or greater than a predetermined value;
- and
- verifying an object information of a peripheral CU of the current CU or an object information of a reference CU of the current CU, and predicting a division structure of the current CU based on the object information of the peripheral CU or the object information of the reference CU, when the current CU is composed of a single object.
A method for encoding an image using a depth information, the method comprising:
- obtaining an object information of a largest coding unit (LCU) from a depth image;
- predicting division structure candidates of the LCU based on the object information;
- and
- deciding an optimum division structure among the division structure candidates of the LCU based on at least one of coding efficiency and display quality.
An apparatus for encoding an image using a depth information, the apparatus comprising:
- an object information verifying portion that verifies a size of a current coding unit (CU), and verifies whether or not the current CU is composed of a single object based on an object information of the current CU obtained from a depth image when the size of the current CU is equal to or greater than a predetermined value;
- and
- a division structure prediction portion that verifies an object information of a peripheral CU of the current CU or an object information of a reference CU of the current CU, and predicts a division structure of the current CU based on the object information of the peripheral CU or the object information of the reference CU, when the current CU is composed of a single object.
A method for encoding an image using a depth information, the method comprising:
- an objection information verifying portion that verifies an object information of a largest coding unit (LCU) from a depth image;
- a division structure prediction portion that predicts division structure candidates of the LCU based on the object information;
- and
- an optimum division structure decision portion that decides an optimum division structure among the division structure candidates of the LCU based on at least one of coding efficiency and display quality.
