说明：  用计算机模拟四步相移的数字全息图，并取得他的包裹相位(Computer simulation of the four-step phase shifting digital hologram, and made him the wrapped phase)

说明：  SLM算法的ccdf表示，用来降低OFDM系统中papr值。(SLM ccdf algorithm, used to reduce the OFDM system papr value.)

这是我在学习过程使用到的一些程序，希望对大家有所帮助!(This is what I used in the learning process some of the procedures, I hope all of you to help!)

这是一个改进的自适应canny算法，该方法采用改进的开关型中值滤波器对图像做去噪工作，再把整幅图像分割为若干子图像，最后在充分考虑全局以及各子图像的边缘梯度信息后，自适应地生成动态阈值。(The new Canny adaptive method divides image into sub-images,then determinates the thresholds automatically according to the whole image edge information and the sub-images edge information.)

this is the start casecade program. it is very useful for beginer.

希尔伯特黄变换是，hilbert+emd的综合。本文件是典型的hht的程序(The Hilbert yellow transformation is the synthesis of hilbert+emd. This file is a typical HHT program)

说明：  FM调制解调(FM modem)

大量matlab实例代码，适合初学者学习matlab程序(Substantial examples of code, suitable for beginners to learn matlab program)

水准网平差MATLAB程序，适合于闭合、附和、支导线(MATLAB standard network adjustment procedures, suitable for closure, they endorse, support wires)

基于视频序列的粒子滤波跟踪程序，首先选中目标图片，有仿真结果(target tracking based on particle filtering)
