随机信号功率谱分析
理解随机信号功率谱分析原理和方法。
(1) 生成信号，被淹没在在噪声中；
(2) 试用周期图法估计信号的功率谱；
(3) 选用不同窗，使用修正周期图法估计信号的功率谱；
(4) 对一段语音信号，使用LD算法估计其功率谱；
(5) 详细列出功率谱估计的步骤和原理。
(understanding of random signal power spectrum analysis principles and methods. (1) generate signals being drowned in the noise; (2) The probationary period plan estimates the signal power spectrum; (3), different windows, the use of map amendment cycle method to estimate the power spectrum signal; (4) a voice signal, the use of LD algorithm to estimate the gong spectrum; (5) a detailed breakdown of the power spectrum estimation steps and principle.)

denoise
Denoising
Reduces the total-variation of the image. Filters out noise while preserving edges. Textures and fine-scale details are also removed. In this demo the assumption is that a white Gaussian noise is added with a-priori known (or estimated) noise power (variance). The fidelity term to the input image is calculated automatically so that the power of the noise is reduced.
