GaussianNoise_LognormalNoise

　　　以X射线检测焊缝图像为研究对象，针对石油焊管管端焊缝生产检验 中线阵列探测器实时成像的X射线数字图像存在的对比度不高、图像噪声及背景 起伏较大、焊缝边缘模糊且纹理较多的特点。(　　This task takes the X一ray weld seam image as the research object, in view of the X一ray image characteristics of low contrast, high image noise and fluctuated background, fuzzy weld seam edge and more texture with linear diode arrays real一time imaging in the petroleum welded pipe.Matlab simulation software is used to analysis methods of smoothing noise, gray transform enhancement, and image segmentation for image processing.)

matlab实例，带通，阻带频率[900,6000] Hz，阻带最小衰减50dB。待滤波的原信号的产生和开始滤波程序。学习使用(matlab instance, band-pass, stop-band frequency [900,6000] Hz, stopband minimum attenuation of 50dB. Generated and the start of the original signal to be filtered filtering process. Learning to use)

陆吾生教授短期课程“压缩感知方法及其在稀疏信号和图像处理中的应用”资料，使用的源码，有参考价值(Professor Lu Wusheng Short Course " compressed sensing method and the sparse signal and image processing applications," the source data, the use of a reference value)

对于利用MATLAB标定工具箱得出相机标定参数后，此函数可利用标定得出的结果，对图像进行畸变矫正，输出矫正好的图像。(Calibration Toolbox for use MATLAB camera calibration parameters obtained, this function can be calibrated using the results obtained, the image distortion correction, output correction a good image.)

构建模型，并进行中断概率matlab仿真(Build the model for matlab simulation, solve the probability of interruption)

EMD分解的matlab代码，克服了传统筛选停止准则中的分母为零的问题(Empirical Mode Decomposition based on matlab)

for embedding text in image

说明：  主要是些简单的数字图像处理中基本的知识点(Mainly some simple digital image processing knowledge of the basic points)

Binary Subtraction performs binary subtraction for two bit arrays and produces back the result, can be used if you represent your bits/symbols as array elements.

地震中常用的一些偏移程序，挺有用处的，跟大家分享一下(Seismic shift in a number of commonly used procedures, quite useful to share with you)
