取阈值常用的方法有：双峰法、迭代法、大津法（OTS(threshold for commonly used methods : bimodal, iteration, Tianjin (OTS. )

一个LED大屏幕接收卡的完整设计工程,有需要学习LED大屏幕控制的朋友可以参考

PCB板检测的大概流程如下：首先存储一个标准PCB板图像作为参考标准，然后将待检测的PCB板图像进行处理，比较与标准PCB图像的差异。根据差异的情况来判断缺陷类型。(The approximate process of PCB board detection is as follows: first, a standard PCB board image is stored as a reference standard, and then the PCB board image to be detected is processed to compare the difference between the standard PCB image and the standard image. The type of defect is judged according to the difference.)

此程序是应用于图形图像处理，基于matlab软件的二维高斯滤波算法实现。(This program is applied to graphics and image processing, based on MATLAB software two-dimensional Gauss filtering algorithm.)

利用广义S变换求取地震信号时频谱，参数可调，代码清晰，用途广泛(The generalized S transform is used to get the time spectrum of signals, and the parameters can be adjusted.)

说明：  该方法在传统的极化SAR滤波Lee方法上增加了自适应窗口处理以及滤波参数预估计等步骤，有效的提高了传统的滤波方法的抑制相干斑的能力，同时能够很好的保持极化SAR图像的极化散射特性。(in the traditional method of increasing polarization SAR Lee adaptive filtering window processing and pre-filtering parameters estimation step, effectively improve the traditional filter method of inhibiting the ability to spot coherent while being able to maintain a good polarization scattering characteristics of SAR images.)

说明：  用于计算图像的空间频率和空间频率图（可看作是图像的轮廓）(Used to calculate the spatial frequency and spatial frequency graph of the image)
