Abstract :
Multi-resolution image analysis by Fast Fourier Transform (MFFT) algorithm has been presented and evaluated for pixel level image fusion. The idea is to apply simple and proven technique of FFT to image fusion. The performance of this algorithm is compared with that of well known wavelet based image fusion technique. It is observed that the performance of image fusion by MFFT is slightly better than wavelet based image fusion algorithm. It is computationally very simple and it could be well suited for real time applications.
