This work aims to clarify the character and selection of repair papers, based on fibre orientation information of paper cultural properties under restoration; using nondestructive image analysis applied to micrographs of paper surfaces. Image analysis using fast Fourier transform with suitable modifications was demonstrated to be an effective means to determine angle and intensity of fiber orientation as a nondestructive method. In the case of contemporary repair papers, the Japanese handmade paper exhibited a high anisotropy value, while the Korean handmade papers exhibited low anisotropy values. Korea and Japanese traditional hand making papers were well distinguished. Korea and Japanese papers made in the traditional ways showed its own characteristic orientation behavior in accordance with the motion of a bamboo wire.
