说明：  利用算数编码基本原理及其实现步骤，通过MATLAB实现算数编码。(Using the basic principle of arithmetic coding and its implementation steps, arithmetic coding is realized by MATLAB.)

实现彩色图像的N*N 中值滤波器，可选择滤波系数。(To achieve the N* N color image median filter, selectable filter coefficients.)

PIVlab是一个开源的粒子图像测速（PIV）软件。它不仅能够通过图像对计算出速度，而且能够得到、显示和导出多个参数的流动模式。通过一个友好的图形用户界面（GUI），使得的PIV技术分析和数据后处理更加快速、高效。(PIVlab is an open-source particle image velocimetry (PIV) software. It can not only calculate the speed through the image pairs, but also can get, display and export the flow patterns of multiple parameters. Through a friendly graphical user interface (GUI), the PIV technology analysis and data post-processing are faster and more efficient.)
