Abstract
A method of creating a texture map is provided. The method includes extracting feature points of a particular object from one or more image frames captured by a camera; selecting one of the image frames as an image frame to be used in the creation of a texture map of the particular object based on information regarding the extracted feature points; and creating the texture map of the particular object using the selected image frame.
Claims15
A method of creating a texture map, comprising:
- extracting feature points of an object from at least one image frame captured by a camera;
- selecting the at least one image frame captured by the camera as an image frame to be used in the creation of a texture map of the object based on information regarding the extracted feature points;
- and
- creating the texture map of the object using the selected at least one image frame.
A method of creating a database for face recognition, comprising:
- calculating vertex coordinates of a mesh corresponding to each pixel of a standard UV texture map using a three-dimensional (3D) standard face model and the standard UV texture map;
- extracting feature points of a face from at least one image frame;
- selecting one of the at least one image frame as an image frame to be used in the creation of a texture map of the face based on the number of extracted feature points;
- creating the texture map of the face using the selected at least one image frame;
- creating a 3D model of the face by performing texturing using the texture map of the face, the vertex coordinates, and the 3D model of the face;
- and
- creating the database using the 3D model of the face and a rendering technique.
An apparatus for creating a texture map, comprising:
- a feature point extraction unit configured to extract feature points of an object from at least one image frame captured by a camera;
- a frame selection unit configured to select at least one image frame captured by the camera as an image frame to be used in the creation of a texture map of the object based on information regarding the extracted feature points;
- and
- a texture map creation unit configured to create the texture map of the object using the selected at least one image frame.
