Abstract
Illusion have been used in many works of art and entertainment products. To understand illusion better, we propose a support tool for Trick-Art production. Especially, we focused on the illusory motion in a still image. To clarify the condition that causes the illusion, we investigate and analyze the mechanism of the illusion effect. Our work is based on the optimized Fraser-Wilcox illusion. We observe the illusion effect using illusion unit pattern and changing the attribute of the pattern, for example, placement, shape and size. As the result, we obtained the knowledge about the condition which causes the illusion strongly. Using this knowledge, we developed a support tool for illusion production. Our tool makes it possible to create illusion products using the image specified by users as the illusion unit pattern.
