This paper presents several results of investigations to find effective image processing methods for decoding mokkans. Mokkans are wooden tablets with handwritten characters excavated from ruins of ancient cities in Japan. Historical mokkans are important cultural properties. Several image processing methods have possibilities to support reading the mokkans damaged heavily. For example, Gaussian blurring is effective when used in conjunction with contrast enhancement in the HSV space. We have also identified several techniques that allow convenient extraction of character strokes in mokkan images. Constructing image processing systems to aid archaeologists and historians is our future work.
