We describe the application of slant correction to handwritten Japanese address recognition. Horizontal strokes of Japanese characters in handwritten Japanese addresses often have a slant to the right upper direction. We propose an iterative modified 8-directional chain code method, that is adapted to slant estimation for these addresses. Recognition experiments for the IPTP cdrom2 database are performed to evaluate the effectiveness of slant correction. Comparative results show that based on slant correction, the accuracy of character segmentation and recognition are both improved, which lead to the accuracy improvement of address recognition.
