try this first to do image segmentation for you. Its very easy to follow.

求信号频谱的源程序，使用傅里叶变换使得减低噪声的源程序。(qiu xin hao pin pu de yuan cheng xu,li yong fu li ye bianhuan jiandi zaosheng)

说明：  计算弹性波带隙结构，主要针对二维的弹性波计算z方向的带系结构(Calculation of elastic wave band-gap structures, mainly for two-dimensional calculation of the elastic wave with the direction z structure)

说明：  直接法求双谱，间接法求双谱，还有基于AR模型法求双谱。程序里面还提供了一种很方便的求对角线谱的方法，大家可以借鉴。总之，你下载了，绝对不后悔的。(Direct method bispectrum, bispectrum Indirect Method, as well as AR Model Method based on dual spectrum. Program which also provides a convenient way to find the diagonal spectrum, we can learn from. In short, you download, and definitely do not regret it.)

matlab huffman encoder

实现图像中值滤波、均值滤波等图像处理功能(Median filtering of image processing functions such as image)

极化敏感阵列的误差估计矫正函数 可以实现在误差较大的情况下仍然可以准确参数估计(Polarization sensitive array error correction function can be achieved is estimated in the case of error is larger still be accurate parameter estimation)

利用matlab语言，采用动态规划算法解决机器设备的调度问题，运行速度快，运行结果完美。(analyzes the allocation of resources in dynamic programming with Matlab , and conducts procedure designs and computation with Matlab , simplifying complex issues and avoiding the cumbersome calculations to make more convenient solutions to problems .)

说明：  假设每个延时单元延时10ms.被传输的基带信号x(t)是一个0，1交替变换的矩形二进制脉冲序列，脉宽为10ms，并假设x(t)通过一个稳定的散射信道后才到达均衡器，成为2径信号，这两路信号幅度相等 ，相隔15ms。用MATLAB实现一个2级LMS均衡器(equalizer)

对于QPSK性能分析的源码,最后给除2种信道下的误码率比较图(QPSK performance analysis for the source, the final addition to the two types of channel bit error rate plan)
