In sound processing, the mel-frequency cepstrum (MFC) is a representation of the short-term power spectrum of a sound, based on a linear cosine transform of a log power spectrum on a nonlinear mel scale of frequency.

THIS IS THE MATLAB SOURCE CODE

This Matlab code implements an edge based geometric active contour model without reinitialization. MATLAB Release: R13SP1 This Matlab code implements the level set method in Chunming Li et al s paper "Level Set Evolution without Re-initialization: A New Variational Formulation", in IEEE Proc. of CVPR 2005. EVOLUTION.m: core function that performs level set evolution. Demo1.m: a demo for a real cell images Demo2.m: a demo for a synthetic noisy image Demo1_ManualBinaryInitial: demo for the same image in Demo1, allows manual initialization by the user Demo2_ManualBinaryInitial: demo for the same image in Demo2, allows manual initialization by the user

matlab产生海洋随机粗糙面的函数 输入参数为 长度 点数 Ku Kl 风速(matlab generate random rough surface ocean input parameters of function points for the length of the wind speed Ku Kl)

利用谱减算法实现对航空录音的处理。主要思想是相对语音进行加噪声，然后再利用算法去噪声，比较前后信噪比的变化。根据实验结构，去噪效果明显。(The use of spectral subtraction algorithm for handling aviation record. The main idea is to increase the relative voice to the noise, and then use the algorithm to noise, signal to noise ratio before and after the change. According to the experimental structure, de-noising effect is obvious.)
