Abstract
A Walsh transformation pair technique is used to analyze the shape features of linear drawings, providing superior shape extraction for angular features. This method employs real number calculations only, but at lower computational cost than previous techniques. Difficult shape deformation (transformation of squarish shapes) can be performed easily using this method. Feature analysis and shape deformation for linear drawings of arbitrary shapes are comparable to previous methods, and the transformation of various shapes can be achieved by combining the proposed method with previous methods.
