说明：  编码规范指导，及代码编写经验分享 编码规范指导，及代码编写经验分享(Elements of Programming Style )

说明：  lab颜色模型下的图像分割方法，在matlab下编写，对生物图像很有用的。(lab model of color image segmentation methods in Matlab to prepare for biological images very useful.)

一系列展示图像压缩技术的源代码。包括有：使用块截断编码的图像压缩(Block Truncation)、基于高斯金字塔变换的图像压缩(Gaussian Pyramids)、基于离散余弦变换对图像压缩(Discrete Cosine Transform)、基于奇异值分解(SVD)的图像压缩(Singular Value Decomposition)。给出的代码还可以用于2D图像噪声消除。(Image Compression A collection of simple routines for image compression using different techniques. BTCODE: Image compression Using Block Truncation Coding. PYRAMID: Image compression based on Gaussian Pyramids. DCTCOMPR: Image compression based on Discrete Cosine Transform. IMCOMPR: Image compression based on Singular Value Decomposition. The given codes can be also used in 2D noise suppression. Notes: The function "conv2fft" performs a 2D FFT-based convolution. Type "help conv2fft" on Matlab command window for more informations.)

Pass the specification values to the object rather than accepting the default values for N, Fc1, and Fc2. Include the sampling frequency Fs as the final input argument. Design the filter and plot the results.

功率谱求法，代入函数后使用此方法求解功率谱。(Power Spectral Method.)

matlab基础例程，用于matlab/simulink通信仿真，代码很典型。(Basic matlab routines, used for matlab or simulink comm simulation, codes are very typical.)

灰度变16进制包含了多种功能是各种代码中必要的一步(Grayscale variable hexadecimal system contains many functions, which is a necessary step in various codes.)

说明：  IEEE官网上的关于UWB的源代码，由于信道仿真，对研究UWB室内定位的用户很有帮助(IEEE UWB official line on the source code, because channel simulation, the study of UWB indoor positioning the user helpful)

一个自适应软阈值去噪的原程序，很实用，我用它解决了很多问题(An adaptive soft-threshold denoising of the original program)
