Abstract: PURPOSE: An image based hand detecting apparatus and method thereof are provided to accurately detect a hand in the dark by creating a comparing result. CONSTITUTION: A hand image detecting unit(50) detects the hand image of a hand shape from an input image. A feature point extraction unit(60) extracts a feature point from the detected hand shape. An image rotation unit(70) rotates the detected hand shape or the stored hand images. A matching unit(80) compares the detected hand image with the stored hand image. When a hand image matched with the detected hand image is existed, a hand shape recognition unit(90) selects the hand image as the matched hand image.

Abstract: PURPOSE: An apparatus and a method for detecting an upper body pose and a hand shape are provided to grasp peripheral environments in 3 dimension when using at least two cameras. CONSTITUTION: A stereo vision computing unit(300) calculates three dimensional distance information from the image provided form at least two cameras(101-103), and a color pattern classification unit(400) outputs the color information and the pattern information by classifying the color and the pattern from the images. Plural location detecting units(610-650) extract 3D location information for each target, and an upper body pose recognition unit(710) recognizes an upper body by using the 3D location information for each target. A hand shape recognition unit(720) recognizes the shape of a hand by using the hand location information.
