Design of Japanese Kimono (Yukata) using an Interactive Genetic Algorithm

Maiko SUGAHARA* Mitsunori MIKI** and Tomoyuki HIROYASU***

(Received January 20, 2009)

In recent years, the design of yukata changed from the fixed traditional designs to various designs. People are interested in the design of yukata. It is useful to design a yukata suitable for each preference. But, in many cases, people have ambiguous image for their favorite yukata, it is difficult to make their favorite design. We propose a yukata design system using an Interactive Genetic Algorithm (IGA). The proposed system is for designing a yukata to suit user’s taste. From the assessment experiment of the system, it was found that the proposed system proved to be effective in the designing of a yukata. In addition, we proposed additional functions that allow obi (sash) color mutation partially in search for the solution. And the experimental results showed the effectiveness of the additional functions.

Key words Optimization, Interactive Genetic Algorithm, Yukata design system, Color combination
