Abstract: An effect processing unit using a style line capable of expressing the effect that a person seems to draw is provided to determine the shape of the directly in-line by three control points and generate a curve by reflecting the curvature of both ends and the curve based on three control points. A contour line generating unit(100) extracts an edge list in a polygon of a 3D object. The contour line generating unit produces the contour line by using the location information of the camera and the extracted edge list. The style line generating unit(110) groups the extracted edge list. The style line generating unit sets up each group as one line. The style line generating unit produces each by group style line by transforming the set up each line. An effect processing unit(120) expresses the line style by inserting the style line into inside and outside of the contour line.

Abstract: An apparatus and a method for recognizing a marker by taking the change of illumination and the interaction of a leaner into consideration are provided to divide the internal area of a marker into a small number of sections to avoid inter marker confusion, thereby improving the recognition performance of the marker. A flip correction module(111) determines the flip state of an input image and corrects the flip of the image. A frame index determining module(112) checks the frame index of the corrected image to determine if the frame index represents the first frame. A marker recognition module(113) recognizes a marker by using the information of a present input frame if the corrected image is the first frame. The marker recognition module(113) performs an adaptive binarization scheme to perform marker recognition based on the change of illumination, history-based information, and the arrangement structure of a marker if the corrected image is not the first frame.
