One of the aspects of the present disclosure discloses an apparatus for recognizing expression of a face in a face region of an image, comprising: a unit configured to detect feature points of the face in the face region of the image; a unit configured to determine a face shape of the face in the face region based on the detected feature points; a unit configured to determine a group that the face in the face region belongs to based on the determined face shape and pre-defined shape groups; and a unit configured to determine an expression of the face in the face region based on pre-generated first models corresponding to the determined group and features extracted from at least one region in the face region, wherein the at least one of the regions are regions which are labeled out in the pre-generated first models corresponding to the determined group.

Apparatus and method for recognizing expression of a face, image processing apparatus and system

One of the aspects of the present invention discloses an image processing apparatus and an image processing method. The image processing apparatus comprises: an image acquisition unit configured to acquire an image containing a face; a region location unit configured to locate at least one region which represents attributes of the face in the acquired image; a feature extraction unit configured to extract features from the located regions; and a feature integration unit configured to integrate the features of the located regions which are symmetrical with each other based on symmetry of the face. According to the present invention, the dimension of the features used for image processing could be reduced and the image processing accuracy could be maintained as much as possible.
