Object image correction apparatus and method for object identification

An object image correction method for identifying an object adapted to an object image correction apparatus, comprising:

• in the object image correction apparatus, an image capturing unit capturing an image and the image is buffered in a memory of the object image correction apparatus;
• in the object image correction apparatus, an object-position identifying unit detecting one or more facial positions on the image retrieved from the memory;
• in the object image correction apparatus, an object-feature identifying unit detecting positions of a plurality of facial features of the faces, wherein the facial features at least include eyes and mouth;
• in the object image correction apparatus, a feature-position computing unit computing positions of the plurality of feature points of the facial features;
• in the object image correction apparatus, a position-deviation judging unit determining one or more degrees of deviations according to the plurality of feature points, wherein the deviations include a shift deviation, a rotation deviation, a scaling deviation, and a direction deviation with regard to the one or more faces by comparing the one or more deviation with a corresponding default value with non-deviation, in which a shift correction process regarding the shift deviation, a rotation correction process regarding the rotation deviation, a scaling correction process regarding the scaling deviation, or/and a direction correction process regarding the direction deviation are performed;
• and
• computing the positions of the feature points after corrections made by a correction unit of the object image correction apparatus, wherein the correction unit includes one or in combination of a rotation correction unit, a direction correction unit, a scaling correction unit, and a shift correction unit.

An object image correction apparatus for identifying an object, and used for capturing, identifying, and correcting an image for fast identification, the apparatus comprising:

• an image capturing unit for capturing the image which is buffered in a memory;
• an object-position identifying unit for reading image signals buffered in the memory, and identifying a position of the object in the image by performing an image processing procedure;
• an object-feature identifying unit for receiving the position of the object from the object-position identifying unit and identifying the object features;
• a feature-position computing unit for computing the positions of the object and the object features;
• a position-deviation judging unit determining whether the object has a position deviation by referring to the object features;
• and
• a correction unit for correcting deviation of the object's position, wherein the correction unit includes one or in combination of a rotation correction unit, a direction correction unit, a scaling correction unit, and a shift correction unit.
