Abstract
A system, article, and method to provide facial expression recognition using linear relationships within landmark subsets.
Claims25
A computer-implemented method of facial expression recognition, comprising:
- obtaining image data of at least one image that comprises content having at least one person's face;
- determining at least one subset of landmarks for two or more main landmarks, wherein each landmark has data to indicate information about a facial feature of the face and wherein the subsets overlap so that one or more landmarks of the subset of landmarks is a main landmark with its own subset of landmarks;
- determining a relationship among each main landmark and its own subset of landmarks;
- and
- using a learned discriminative model to label a facial expression class for the face by using the relationships.
2 more elements
A computer-implemented system of facial expression recognition comprising:
- a display;
- at least one processor communicatively coupled to the display;
- at least one memory communicatively coupled to at least one processor and storing image capture data of at least one frame of a video sequence or at least one still photograph;
- and
- at least one facial expression recognition unit communicatively coupled to the processor, and to:
- obtain image data of at least one image that comprises content having at least one person's face;
- determine at least one subset of landmarks for two or more main landmarks, wherein each landmark has data to indicate information about a facial feature of the face and wherein the subsets overlap so that one or more landmarks of the subset of landmarks is a main landmark with its own subset of landmarks;
- determine a relationship among each main landmark and its own subset of landmarks;
- and
- use a learned discriminative model to label a facial expression class for the face by using the relationships.
7 more elements
At least one non-transitory computer readable article comprising a plurality of instructions that in response to being executed on a computing device, causes the computing device to:
- obtain image data of at least one image that comprises content having at least one person's face;
- determine at least one subset of landmarks for two or more main landmarks, wherein each landmark has data to indicate information about a facial feature of the face and wherein the subsets overlap so that one or more landmarks of the subset of landmarks is a main landmark with its own subset of landmarks;
- determine a relationship among each main landmark and its own subset of landmarks;
- and
- use a learned discriminative model to label a facial expression class for the face by using the relationships.
