Abstract
A method of determining a facial expression type may include extracting feature points representing facial characteristics from a facial image of a user; grouping the extracted feature points into a plurality of regions; and determining a facial expression type for each of a plurality of groups using feature points and a facial expression type function corresponding to each of the groups.
Claims20
A method of determining a facial expression type, the method comprising:
- extracting feature points representing facial characteristics from a facial image of a user;
- grouping the extracted feature points into a plurality of regions;
- and
- determining a facial expression type for each of a plurality of groups using feature points and a facial expression type function corresponding to each of the groups.
A method of generating a facial expression type function which generates a facial expression type function, the method comprising:
- receiving facial images of a plurality of users;
- extracting feature points corresponding to regions of the users from the facial images of the users;
- generating facial expression types using the feature points corresponding to the regions of the users;
- representing the generated facial expression types in a normal distribution and classifying the facial expression types according to a preset criterion;
- and
- generating a facial expression type function using the classified facial expression types.
A non-transitory computer-readable recording medium recording a program to implement a method of generating a facial expression type function, the method of generating the facial expression type function comprising:
- receiving facial images of a plurality of users;
- extracting feature points corresponding to regions of the users from the facial images of the users;
- generating facial expression types using the feature points corresponding to the regions of the users;
- representing the generated facial expression types in a normal distribution and classifying the facial expression types according to a preset criterion;
- and
- generating a facial expression type function using the classified facial expression types.
An apparatus for determining a facial expression type, the apparatus comprising:
- an extraction unit to extract feature points representing facial characteristics from a facial image of a user;
- a grouping unit to group the extracted feature points into a plurality of regions;
- and
- a facial expression type determination unit to determine a facial expression type for each of a plurality of groups using feature points and a facial expression type function corresponding to each of the groups.
An apparatus for generating a facial expression type function which generates a facial expression type function, the apparatus comprising:
- an input unit to receive facial images of a plurality of users;
- an extraction unit to extract feature points corresponding to regions of the users from the facial images of the users;
- a facial expression type generation unit to generate facial expression types using the feature points corresponding to the regions of the users;
- a classification unit to represent the generated facial expression types in a normal distribution and to classify the facial expression types according to a preset criterion;
- and
