This paper proposed a new feature extraction method for Chinese character recognition by using Gabor filters.Based on the theory of Gabor filters and the statistical information of Chinese character images
an effective method to design Gabor filters was developed.Moreover
to improve the performances for low quality images
non-linear functions were designed to regulate the outputs of Gabor filters adaptively.This paper also improved the feature extraction method to enhance the discriminability of histogram features.Experiments show that our method performs excellently for images with noises
backgrounds or stroke distortions and can be applied to printed or handwritten character recognition tasks in low quality greyscale or binary images.
