Outline of Final Research Achievements

In this study, we aim to develop a system to help human-human communicatoin for super-aging society. We developed edge-preserving filtering, which is robust for light fluctuation in image processing area. We also investigated the effectiveness of parameter setting using speech recognition system directly.
As results, we improved a filter combining edge-preserving filter and self-quotient filter. We also confirmed the effectiveness of the parameter setting using speech recognition system.
