In this paper,a handwritten radical recognizer,with the purpose of obtaining reliable radicals in on-line Chinese words or sentences recognition task,was designed based on a hybrid method of Level-Building (LB) and Dynamic Time Warping(DTW) algorithm.Radicals were considered as mid-patterns between strokes and continuous handwritten script in the recognizer.A handwritten radical set was established in terms of handwritten script characteristics.Adjacent stroke relative feature vector sequences were put into the grid point matching process of DTW in each level of LB structure.The test samples include 303 handwritten sequences and 6 763 Chinese characters.It is shown that the radical set could be in effect between strokes and a handwritten sequence,86.47% of recognition rate is obtained.
