这是一个关于齿轮的齿顶圆和齿根圆半径的计算程序，先将图片预处理和二值化，然后进行边缘检测求出圆心，最后用平均法求出半径。(This is an addendum on the gear tooth root radius circle and the calculation procedure, the first image preprocessing and binarization, edge detection and then find the center of a circle, with the final calculated average radius.)

说明：  OQPSK的Matlab/Simulink调制解调仿真系统，包括匹配滤波，载波恢复，定时恢复等重要模块，可以观察眼图，仿真误码率，帮助理解OQPSK系统(OQPSK Matlab/Simulink simulation system modulation and demodulation, including matching filter, Carrier Recovery, timing recovery and other important module, we can observe the eye, simulation BER help understand OQPSK system)

有损图像压缩的matlab程序实现，通过dct变换，霍夫曼编码，译码，比较压缩后图像与原图。(lossy image compression)
