| Abstract(in English) | We propose a gray-scale character recognition method using Gabor filter. In our method, features are derived by accumulating edge components in local region of output of Gabor filters. This method is robust for charcter positioning errors and can recognize low-resolution characters precisely. The average of recognition rate is 88.8% for 865 alphabets obtained from seven films. We also experiment on characters with positioning errors. From the result, proposed method is robust for displacement less than 5% of character size. It shows that this method is useful for video caption recognition. |
