Abstract
A method and system for detecting facial expressions in digital images and applications therefore are disclosed. Analysis of a digital image determines whether or not a smile and/or blink is present on a person's face. Face recognition, and/or a pose or illumination condition determination, permits application of a specific, relatively small classifier cascade.
Claims20
A method of in-camera processing comprising:
- acquiring one or more images;
- identifying one or more faces in the one or more images;
- from among the one or more faces, identifying a particular number of non-smiling faces;
- based, at least in part, on the particular number, initiating one or more operations.
A portable digital image acquisition device, including a lens and an image sensor for acquiring digital images, a processor, and one or more processor-readable media have code embedded therein for programming the processor to perform a method of in-camera processing, wherein the method comprises:
- acquiring one or more images;
- identifying one or more faces in the one or more images;
- from among the one or more faces, identifying a particular number of non-smiling faces;
- based, at least in part, on the particular number, initiating one or more operations.
One or more non-transitory processor-readable media having code embedded therein for programming a processor to perform a method of in-camera processing, wherein the method comprises:
- acquiring one or more images;
- identifying one or more faces in the one or more images;
- from among the one or more faces, identifying a particular number of non-smiling faces;
- based, at least in part, on the particular number, initiating one or more operations.
