要約 Camera-based character recognition has a possibility to realize a variety of applications and has been paid attention. However, character images are often taken from different angles and characters tend to be distorted. In such a case, recognition accuracy becomes worse. Therefore, we must find some methods to deal with this problem. In this paper, we experimentally evaluate some affine-invariant local descriptors by testing how well they can recognize affine distorted characters. As a result, affine-invariant local descriptors are robust to affine distorted characters to some extent.
