Abstract: A method of recognizing a user's dynamic organ for use in an electric-using apparatus includes scanning a target image inputted through an imaging element using a window; generating a HOG descriptor of a region of the target image that is scanned when it is judged that the scanned region includes a dynamic organ; measuring 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 judging that the scanned region includes the gesture of the dynamic organ when the resemblance value meets a predetermined condition.
