Ch1-Introduction

超声声场的线性描述与仿真工具，可以作为超声系统的研究有用工具，根据不同的输入 ，得到不同的超声图像，验证自己的算法。(The linear ultrasonic sound field description and simulation tool that can serve as a useful tool for study of ultrasound systems, depending on the input, get a different ultrasound images to verify their algorithms.)

说明：  用小波多尺度分析进行基于医学图像形状特征的检索.(wavelet multiscale analysis based medical image retrieval features of the shape.)

描述ＥＤＧＥ系统接收机结构，包括prefilter和均衡器(Description EDGE receiver structure, including the prefilter and the equalizer)

It is a matlab code for K Nearest Neighbor algorithm.

EDGE PRESERVING SMOOTHING

空间上为高斯型的连续平面波入射到一薄金属层上的透射情况(Space for the continuous Gaussian plane wave incident on a thin metal layer on the transmission case)

说明：  本压缩文件提供了matlab的时间序列工具箱，内有程序详细说明(the compressed files provided Matlab Toolbox time series, which detailed procedures)

matlab图像彩色处理，主要有三基色的调用，调整，以及图像的伪彩色增强(matlab image color processing, there are three primary colors of the calls, adjustments, and pseudo-color image enhancement)

说明：  10种比较经典的数字滤波C程序，比较有用(Comparison of 10 C classical digital filtering procedures, more useful)
