摘要: 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.

摘要: A digital still image camera having a memory means functioning as a ring buffer. Image and sound acquisition and storage begins upon a first command signal from the camera's operator and continues at a defined rate until the operator generates a second command signal. During the time period between the first and second command signal, images are taken and stored at the defined rate, the newest image overwriting the oldest image within the ring buffer after the ring buffer is initially filled. After generating the second command signal, the operator can review the contents of the ring buffer on a display and speaker incorporated into the camera, selecting those images and sounds the operator wishes to store permanently, and then directing that the selected images and sounds be placed in the camera's long term storage memory.

摘要: A method of face categorization and annotation of a face image library includes automatically cropping a face within an acquired digital image or removing one or more non-facial items from the digital image, or both, and thereby generating a full-size face image. The full-size face image is stored with other indicia identifying a person corresponding to the face in a face image library of an embedded device such as a mobile camera phone or other handheld camera device.
