| Outline of Final Research Achievements |
In this research, we aimed to clarify the origin of visual illusion based on nonlinear physics. We recognize that the functions of visual system and its dynamics can be regarded as emerging phenomena self-organized in the system. On the basis of the fundamental approach, we also try to develop new information technology and new application to clinical medicine.
The most important result is understanding of "Motion Sharpening" based on the FitzHugh-Nagumo model (nonlinear reaction-diffusion model). We found that the nonlinear characteristics of the visual system can be replicated by the analysis of the system by investigating input-output characteristics against to very small amplitude input. On the basis of this founding, we proposed a new noise robust method to realize motion enhancement. Application for a patent is under preparation.
