A noise-adaptive discriminant function and its application to blurred machine-printed Kanji recognition

This is the authors' abstract. We don't add key points for this paper.

Accurate recognition of blurred images is a practical but previously mostly overlooked problem. In the paper, we quantify the level of noise in blurred images and propose a modification of discriminant functions that adapts to the level of noise. Experimental results indicate that the proposed method actually enhances the existing statistical methods and has impressive ability to recognize blurred image patterns.
