Method and Interface of Recognizing User's Dynamic Organ Gesture and Electric-Using Apparatus Using the Interface

An interface for use in an electric-using apparatus, the interface comprising:

• an imaging element;
• and
• a dynamic organ gesture recognition portion that scans a difference image, which reflects brightness difference between a target image and a comparative image that are inputted through the imaging element, using a window;
• generates a HOG (histograms of oriented gradients) descriptor of a region of the difference image that is scanned when it is judged that the scanned region includes a dynamic organ;
• measures a resemblance value between the HOG descriptor of the scanned region and a HOG descriptor of a query template for a gesture of the dynamic organ;
• and judges that the scanned region includes the gesture of the dynamic organ when the resemblance value meets a predetermined condition,
• wherein the comparative image is one of frame images previous to the target image.

• wherein the comparative image is one of frame images previous to the target image.
