Analysis of Sensitivity and Diffusion Based on Video Fractional Spectrum

Abstract:

Based on the video data, the paper analyzed the rotation factor sensitivity and diffusion of fractional Fourier transform. During the fractional Fourier transform process, we adopted three ways to process the video data. Through comparison of them, the second way, which is 4byte cast to 1float, is the most suitable for the sensitivity and diffusion analysis. Sensitivity analysis showed that the fractional Fourier transform rotation factor sensitivity and diffusion analysis showed that when any one of elements plus or minus greater than 0.2 times the transform, it would lead to completely fail to recover the original video data of inverse transform.
