Abstract(in English) | Methods for information compression and recognition of line drawings(curves) are proposed. For information compression, very smaller number of points(pixels), in comparison with the number of pixels consisting of a digital curve, are extracted, which are called feature points. The feature points extracted in this paper are zero points of a smoothed curvature function as well as points where the function takes maximum absolute values between adjacent zero points. We see that these points can be extracted stably. By using only the feature points line drawings are recognized in position, scaling and rotation invariant manner. To this end the method developed by authors - a method applying algebraic equations - is adopted. The method has several advantages over. those proposed so far. Experimental results are also shown. |
