Abstract
Provided are an ink data generation apparatus, an ink data generation method, and an ink data generation program that are capable of improving ease of handling ink data when or after metadata is generated. An ink data generation apparatus performs a determination as to an inclusion relation between a first set and a second set by comparing stroke elements of first set data and stroke elements of second set data using the first set data and the second set data. The ink data generation apparatus generates first metadata for the first set described in a form that varies in accordance with a result of the determination.
Claims7
An ink data generation apparatus that generates ink data including metadata describing meta-information regarding each of sets of strokes, the ink data generation apparatus comprising:
- a first acquisition circuit configured to acquire first set data representing stroke elements belonging to a first set, to which the meta-information has not been assigned yet;
- an attribute estimation circuit configured to estimate a semantics attribute to be assigned to the first set, on a basis of mutual relations between positions or shapes of the stroke elements that form the first set;
- a user interface circuit configured to be capable of displaying the stroke elements that form the first set and displaying a user control which enables input of a semantics attribute to be assigned to the first set;
- and
- a data generation circuit configured to generate first metadata for the first set indicating the semantics attribute inputted by the user control or estimated by the attribute estimation circuit.
An ink data generation method for generating ink data including metadata describing meta-information regarding each of sets of strokes, the ink data generation method being implemented by one or a plurality of computers and comprising:
- acquiring a set data representing stroke elements belonging to a set, to which the meta-information has not been assigned yet;
- estimating a semantics attribute to be assigned to the set, on a basis of mutual relations between positions or shapes of the stroke elements that form the set;
- displaying the stroke elements that form the set and displaying a user control which enables input of a semantics attribute to be assigned to the set;
- and
- generating metadata for the set indicating the semantics attribute estimated or inputted by the user control.
An ink data generation program stored in a tangible computer-readable medium for generating ink data including metadata describing meta-information regarding each of sets of strokes, the ink data generation program causing one or a plurality of computers to perform:
- acquiring a set data representing stroke elements belonging to a set, to which the meta-information has not been assigned yet;
- estimating a semantics attribute to be assigned to the set, on a basis of mutual relations between positions or shapes of the stroke elements that form the set;
- displaying the stroke elements that form the set and displaying a user control which enables input of a semantics attribute to be assigned to the se;
- and
- generating metadata for the set indicating the semantics attribute estimated or inputted by the user control.
