 note = {P(論文), This paper describes characteristics of complex FFT (CFFT) and an example of figure analysis by using CFFT. In case that input function is complex (real component is not equal to imaginary component and real component is not zero), CFFT components against complex input function (CIF) have different characteristics from conventional FFT components against real function. In case that outline figure, which is pictured on the surface of complex plane, can be represented by complex function throgh special process, we can treat the function as CIF and can analyze the CIF by using CFFT. As a result, we can analize or recognize pattern of outline figures precisely and effectively.},
