包括：隐藏混沌序列即隐藏参数的生成；对图像进行隐藏；恢复出隐藏前置乱的目标图像；恢复出原目标图像；对隐藏目标置乱处理等(Include: hidden chaotic sequence that is hidden parameter generation images hidden the restoration of a hidden goal of arbitrary pre-image the restoration of the original target image to hide the goal of treatment, such as scrambling)

A fast Fourier transform (FFT) is an algorithm to compute the discrete Fourier transform (DFT) and its inverse. Fourier analysis converts time (or space) to frequency and vice versa an FFT rapidly computes such transformations by factorizing the DFT matrix into a product of sparse (mostly zero) factors.
