Abstract: PURPOSE: A contactless data input using image processing and a manipulation method thereof are provided to easily implement real time by reducing operation quantity and improve user convenience by being strong to environmental changes. CONSTITUTION: A skin color area is formed by extracting a skin color from an input image(S1). A hand area is formed by extracting a hand from the skin color area through comparing object sizes(S3). The centroid and a finger end point of the hand area are extracted by using a centroid method and a flexure technique based on outline information of the hand area(S4). A manipulation motion of a user matches a finger joint with a knuckle and is recognized by measuring length changes of the knuckle and an angle of the finger joint. Data is received by tracing movements of the centroid and the matched finger end point(S6).
