framesubtraction

说明：  对图像进行归一化处理！是图像预处理中不可缺少的重要部分(The image is normalized! Image preprocessing is an indispensable part in)

Modern Spectrum Estimation Nonparametric Methods Minimum Variance Spectrum Estimation etc.

因为傅立叶变换对应的是无限信号,信号经过分帧后变成有限信号,分帧的信号再进行傅立叶变换后,高频部分将有 泄露 ,所以要加窗. 窗函数的拼谱都是在某高频部分截止,所以每帧信号加窗后的傅立叶变化,频谱基本 泄露 (Because Fourier transform corresponding is infinite signals, signals after framing become limited, framing signal again after Fourier transform, the high frequency part will have leaked , so to add window. Window function spell spectrum are in a high frequency part of the globe, so each frame and window after Fourier transform, signal spectrum basic leak )
