ABSTRACT

To hand down the technique of the traditional handicrafts usually takes over a decade. Therefore, the shortage of successors is becoming a serious problem. Thereby there are needs of analyzing the technique scientifically to hand down the technique in less time. FUDE which is Japanese calligraphy brush have been designated as traditional products of Nara prefecture. It is impossible to manufacture high performance brush from a single raw material, however high performance brush can be obtained by blending many kinds of materials with different characteristics. This process of blending filaments with different characteristics is called “KEGUMI”. The next manufacturing process of “KEGUMI” is “KEMOMI”. “KEMOMI” is the work to even up the humidity mixing ratio in all the parts of the filaments bunch. Filaments are not to be able to demonstrate the performance only by mixing the filaments with different characteristics, synergy of high performance only begins to appear when filaments 212are uniformly distributed. In this study “KEMOMI” process was analyzed by the method of Image thresholding and motion analysis.
