Multi Focus Image Fusion using Matlab code

用于心音信号包络的分割，信号处理的技术领域，具体的说，涉及一种心音信号周期的检测与心音的状态分割方法。其中，心音的状态分割方法是在时间维度上判断某时刻某段时长内出现的心音状态的类别。(Envelope Segmentation of Heart Sound Signals)

实现SAR 的二维线性调频信号仿真，方位向、距离向都是LFM信号，脉冲压缩是用时域卷积实现的！(Two-dimensional realization of SAR chirp signal simulation, the azimuth, distance to all LFM signal, pulse compression is achieved using time-domain convolution!)

EMD分解，可以有效的解决EMD分解问题，并嫩而过画出希尔伯特谱(EMD decomposition, can effectively solve the problem of EMD and tender and had drawn Hilbert spectrum)

自动离合器，模型包含制动器，，变速器，主减速器，差速器等子模型及其模糊控制规则(Automatic clutch, the model includes brakes, transmission main gear box, differential and sub-model and its fuzzy control rules)

本设计采用了一种基于三参数组合的方法对语音信号进行了清/浊音判决。在传统两参数（短时能量和过零率）算法基础上增加了自相关函数作为判决参数，减少了清/浊音信号误判率。(This design uses a combination of methods based on three parameters of the voice signals of the Qing/voiced sentence. In the traditional two parameters (short-term energy and zero crossing rate) algorithm based on the increase since the correlation function as a decision parameter, reducing the clearance/voiced signal false positives.)
