两路语音信号混合及解混的基于自然梯度的极大似然算法MATLAB仿真程序(Two-way voice signals mixed and mixed solution of the natural gradient-based maximum likelihood algorithm of the MATLAB simulation program)

摘　要:针对茄子图像的灰度和颜色特点,利用MATLAB中丰富的图像处理函数,分别进行了色差分割和色调分割。在 色调分割中,采用了自动选取阈值的Otsu法。在去除残留噪音的处理中,采用标注的方法对二值图像的各连通区域进行面积 统计。保留最大面积的区域,从而使分割效果大大改善。利用多参数来衡量分割效果,使评价做到最大程度的客观、合理。(Based on the gray- level and color characteristics of eggp lant image, hue and color- difference segmentation were conducted by using the rich image p rocessing functions embedded inMATLAB. The auto threshold- adap tivemethod ofOtsu operation was specially used for hue segmentation. And upon the elimination of the residue noise, labelingmethod for statistical calculation was introduced for the connected regions of the binary image. Themaximum areaswere p reserved to imp rove segmentation effects. In addi2 tion, multi- indiceswere app lied to assess the effect of segmentation, in order to get impersonal and reasonable assessment)

Iterative Solutions is committed to the mission of developing accurate and efficient software for the simulation of modern communication systems. All software is licensed as open source software under the Lesser GPL. The code is designed to run in matlab, though the compute-intensive portions are written in C and Java. A wide variety of error control codes are supported, including turbo and LDPC codes, and an emphasis is placed on nonbinary modulation formats such as QAM and nonbinary continuous-phase FSK. The software goes beyond the usual error rate analysis by including tools for determining the Shannon capacity of arbitrary modulation formats.

matlab 门限模型 这是一个比较好的用matlaB软件做门限模型的方法。(matlab threshold model which is a good software to do with matlaB threshold model.)
