MATLAB 实现图像增强与轮廓提取 摘 要 图像增强是图像处理中最关键的研究问题之一。图像增强其目的是对图像进行 加工，以得到对具体应用来说视觉效果更好更有用的图像。这里的好和有用因具体 的应用目的和要求而异，并且所需要的具体增强技术也可以大不相同。 数字图像中轮廓提取就是对图像外部特征进行提取分析，图像的外部特征包括 的如方向，形状，基础性质等，随着科技的不断发展，人们对事物的内在和外在了 解程度的不断加深，轮廓检测这门技术在图像处理的领域显得格外重要。 最后利用MATLAB 软件设计程序，对图像进行编辑、增强，通过增强后得到的 改善效果分析说明各种增强方法的适用场合、优缺点、实现的难易程度及对增强效 果的控制难易。 关键词： MATLAB，图像增强，轮廓提取 V MATLAB 实现图像增强与轮廓提取 Abstract Image enhancement is one of the most critical reseach in image processing. Its purpose is to get the “better” visual effect and the more “useful” image in concretion application by processing images. The “better” and “useful” should be different by specific application purpose and requirement. And specific needs may vary greatly enhance technical. Contour detection which is the image of the external characteristics extraction, image including the external characteristics such as orientation, shape, based on the nature, as science and technology development, people of the right things, internal and external, understand the extent of the continuous deepening, Contour detection of this technology in the field of image processing is particularly important. Then using the MATLAB to editor and enhancement the image, analyzing enhancement image, the application of occasions, advantages and disadvantages, achieve easily or not, and enhance the effectiveness of the control easy or not.
