Invariant character recognition in Dynamic Link Architecture

A model based on the application of the Dynamic Link Architecture (DLA) is presented for the off-line recognition of Chinese characters. It is a revised DLA model employing 4-vector dynamic link assignment instead of the original 3-vector links. A sample set of Chinese characters was used to test the performance of the model under various transformations including translation, reflection, rotation, dilation and distortion. Challenging results are obtained. An improvement of 40% in recognition rate was attained by using the revised DLA model for Chinese character recognition. On the other hand, for the testing of invariant properties, an overall correct recognition rate of 85% was obtained under various transformations.
