This paper proposes an approach of radical-based online handwritten Chinese character recognition using support vector machine (SVM). In our system, after the input Chinese character is preprocessed, segments ,the structure feature of the character are extracted and the middle point of each segment is projected in horizontal and vertical directions to detect that which type the character's pattern type is of single-element pattern, left-right top-bottom pattern, surrounding or half-surrounding pattern? The character is then decomposed into many meaningful sub-structures. Every substructure is a radical actually and is divided into 8 subareas for each of four directions so that the statistics feature of number of pixels in each subarea is adapted to recognize radical using SVM. Since Chinese character is composed of radicals, the recognition of Chinese character is transformed to series of radical matching between the input character and reference pattern. Furthermore, a character could have front radical and rear radical, so the front or rear radical is utilized in coarse classification stage to reduce the number of candidate characters. In respect that only radicals' feature and the radical string for a character is needed to be recorded, the template file size can be largely reduced, the speed of recognition is improved greatly. In addition, as the structure feature and the statistics feature are both adopted in this system, it is independent on stroke-number and stroke-order.
