在无损检测中,由图像获取系统产生1bit×1bit×12bit（1bit×1.5bit×12bit）的数字图像,将其作为处理对象。应用VC++开发工具,在WIN98/WIN2000平台上建立了图像处理的通用软件枢架。本软件现已实现的基本功能包括:数字图像的滤噪、锐化以及图像的边缘检测。 软件中包括了以下几种处理方法:直方图均衡化、对比度拉伸、非线性中值滤波、低通滤波方法（理想频域、梯形、指数）、高通滤波方法（理想频域、梯形、指数）、理想频域带通滤波方法、差分梯度边缘检测、SOBERL边缘检测、LAPLACE边缘检测,还包括了离散傅立叶
In non-destructive testing, a digital image of 1 bit × 1 bit × 12 bit (1 bit × 1.5 bit × 12 bit) is generated by the image acquisition system as a processing target. Application of VC + + development tools, the WIN98 / WIN2000 platform to establish a common software image processing framework. The software has achieved the basic functions include: digital image filtering, sharpening and image edge detection. The software includes the following several processing methods: histogram equalization, contrast stretching, nonlinear median filtering, low-pass filtering (ideal frequency domain, trapezoidal, exponential), high-pass filtering (ideal frequency domain, trapezoidal, index ), The ideal frequency band-pass filtering method, differential gradient edge detection, SOBERL edge detection, LAPLACE edge detection, but also includes discrete Fourier
