DWT(MATLAB)

开发环境是FPGA开发工具，主要讲解用CPLD/FPGA实现浮点数的运算(Development environment is the FPGA development tools, primarily on the use of CPLD/FPGA to achieve floating-point arithmetic)

This is a MATLAB program for Histogram Matching. Used In digital Image Processing.

helps to find the maximum entropy value to be optimised using PSO. Produces good results than ostu method

This code takes speech as input, removes silence region based on zero crossing rate and energy.output of the code is only voiced region of the input speech signal.the input is of the .wav format.

对四分量的信号进行时频处理，得到小波尺度图、平滑伪wigner图、WVD图。有利于对信号进行很好的分析。(Four components of the signal time- frequency to give Scalogram, smoothed pseudo wigner diagram, WVD FIG. Conducive to good analysis of the signal.)

说明：  并网逆变器下垂控制特性仿真，能正常仿真，波形控制输出有振荡，共学习参考使用。(droop control:The network-connected inverter sagging control characteristics simulation, can be normal simulation, waveform control output oscillation, a total learning reference use.)

根据输入的概率进行香农编码，然后输出必要的参数和编码的结果。其中有嵌套程序。(Probability under the Importation of Shannon coding, and then output the necessary parameters and the coding results. Which have nested procedures.)

use for the mosaic the image by taking the picture at different angale
