Abstract:
1. A method of recognizing a user's dynamic organ for use in an electric-using apparatus, the method comprising: generating a skin color image from a target image inputted through an imaging element; scanning the skin color image using a window; generating a HOG descriptor of a region of the skin color 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, wherein generating the HOG descriptor of the scanned region includes: generating a HOS (high order statistics) map for the scanned region using a HOS information for brightness of the scanned region; and generating the HOG descriptor of the scanned region based upon the HOS map, wherein the HOS information is found through second and third expressions, wherein the second expression is  (where the B(x,y) is a set of a pixel at a coordinate (x,y) and the surrounding pixels, the N wherein the third expression is  (where the UL is a top limit value, and the DSF is a down scaling factor), and wherein generating the skin color image from the target image includes applying a HSI (hue saturation intensity) color model to the target image to generate the skin color image.
