This Two-Category Classifier Using Discriminant Functions to separeate two classes. The Classifier is designed on classes which has two feature vectors and other case it has one feature vector.

用matlab对一张图片进行DFT变换，DCT变换,比较保留20个DCT变换系数重构的图象与原始图像的差别.(Using matlab on a picture to DFT transform, DCT transform, compared to 20 DCT transform coefficients to retain the image reconstruction of the difference between the original image.)

　　　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.)

数字信号处理中的频谱泄露的程序，有助于帮助理解信号滤波处理的内涵。(Digital signal processing procedures spectral leakage, signal filtering helps to help understand the meaning.)
