Most of basic operations in signal or image processing are based on
discrete convolution. Fast Fourier Transform (FFT) is used to implement
discrete convolution in frequency domain in order to reduce
computational complexity, for certain signal and impulse response
durations. FFT needs to add redundant zeros for its operation, since it
is designed for the signals whose duration is power of two. Therefore
the operation sometimes contains many redundant calcurations. This paper
proposes an efficient method using modified frequency domain processing
and compensation in time/space domain which can improve efficiency in
convolution opereation and filtering. Its effectiveness is verified
through some computer simulation and DSP implementation. |
