毕 业 设 计 论 文 图象边缘处理系统 Image edge Processing System 摘 要 本文对图像处理理论进行了深入的分析和研究。图像处理有很多的领域，比如通过对大径原木的分等、高档集成材和地板块的缺陷剔除、珍贵树种原木的最优下锯、大径优质原木旋切的最优定心等传统技术无法解决的高技术问题的研究。本课题利用图像边缘检测与提取及轮廓跟踪技术来识别图像边缘的缺陷。 本课题通过各种算子来实现对图像的灰质进行分析、调节，对某些边缘过于平滑的图像需要进行升燥处理，对某些边缘比较特殊的图像进行边缘的提取以及跟踪。 本论文采用Visual C++6.0程序设计语言，以模块化软件设计技术，运用数字图像处理技术，在Windows平台上设计了图像边缘监测与提取及轮廓跟踪的图像处理系统。本设计针对图像处理进行研究，使用了一系列的可行性算法，获取图像特征参数。构造CDib类（其中封装了多个图像处理函数）以方便的处理位图操作。用Cdib Process View类调用CDib类中的图像处理函数，实现对原始图像的边缘检测，轮廓提取及跟踪。为对木材形状和缺陷进行识别提供了必要的理论前提和技术基础。 关键词 图像处理，边缘检测，轮廓提取，轮廓跟踪，VC++6.0  Abstract The thesis of the theory of image processing conducted in-depth analysis and research. Image processing involve a number of areas. For example, by grading of large diameter logs, high-grade laminated plates and to remove defects, rare species under the optimal sawing logs, large-diameter high-quality wood veneer of the best-centering and other traditional techniques can not solve the problem of high-tech study. The issue of image edge detection and contour extraction and edge tracking techniques to identify defects. Operator of this issue to achieve through a variety of image analysis of gray matter, regulate, to some edges are too smooth, dry rose image processing needs, some more specific image edge extraction and edge tracking. This thesis adoption Visual C++6.0 procedure design language, handles with mold a picture for turning software design technique, application digital image processing technique, on the terrace of Windows designing image edge detection with withdrawing and outline following system. This design aims at the image proceeding studies, using a series of possibility calculate way, obtaining the picture characteristic parameter. Structure CDib (among them sealed to pack several pictures handles function) to handles conveniently a diagram operation. Adjust to handle with the picture in CDib with CDib Process View function, realizes to detect to the edge of the primitive image, the outline withdraws and follows.
