Hideyuki Takagi: Auditory and Visual-based Signal Processing with Interactive Evolutionary Computation. in Machine Intelligence Quo Vadis? -- The Progressive Trends in Intelligent Technologies --, 2nd Euro-International Symposium on Computational Intelligence (E_ISCI2002), Kosice, Slovakia, (June 16-19, 2002).



We discuss new type of signal processing approach, auditory and visual-based signal processing, and show some examples of filter design based on this approach. This approach allows us to design fil- ters based on our auditory or visual evaluation of the filter outputs, while the conventional signal processing is based on mathematical ex- pression. Interactive evolutionary computation is a main technology of this approach, and the evolutionary computation optimizes the target filter based on our auditory or visual inspection to the processed signal. Recovering speech from distorted speech, compensation of hearing im- pairment, and enhancing images are discussed as examples of this new approach of signal processing.
