基于空域处理的图像增强

2014-02-13 02:37 中英文标题、摘要、关键词
摘要：一般情况下，各类图像系统中图像的传送和转换（如成像、复制、扫描、传输以及显示等）总要造成图像的某些降质。必须对这些降质的图像进行改善处理。通常改善方法有两类：一类是不考虑图像降质的原因，只将图像中感兴趣的特征有选择的突出，而衰减其次要信息；另一类是针对图像降质的原因，设法去补偿降质因素，从而使改善后的图像尽可能的逼近原始图像。第一类方法能提高图像的可读性，改善后的图像不一定逼近原始图像，如突出目标的轮廓，衰减各种噪声，将黑白图像转换成彩色图像等。这类方法通常称为图像增强技术。第二类方法能提高图像质量的逼真度，一般称为图像复原技术。本文中讨论的就是这两种方法中的图像增强技术。从图像的基础详细介绍了数字图像，通过一个运用实例，演示了图像增强在现实当中的作用，最后概括了它的特点，并指出它的不足之处。以vc 为编程工具实现了一个图像处理软件，本系统运用了图像平滑、中值滤波、图像锐化、伪彩色编码这四个功能，针对图像的需要选择对应的功能进行处理。图像增强系统的界面比较友好、功能明了、操作简单。

The Image Intensification Based on Air Zone ProcessingAbstract:Generally speaking, all kinds of picture system conveyance and conversion (such as formation of image , duplicate , scan , transmit and reveal ,etc. ) of picture always cause some of the picture to lower the quality. Must be improving and dealing with to these pictures which lower the quality. There are two kinds of to usually improve methods: One to consider picture reason to lower quality , have choose conspicuous characteristic that picture interested in only, and decaying secondly want information; Another to lower reason of quality to picture, try , go , compensate , lower quality factor, thus the picture possible approaching the primitive picture after enabling and improving. The first type method can improve the readability of the picture , the picture after improving might not approach the primitive picture , such as outline to stress goal , decay various noises , change black-and-white picture into colored picture ,etc.. This kind of method is usually called the picture and strengthened technology. The second type method can improve the fidelity of picture quality , is generally called the picture and restored technology. That discuss is that the picture in these two kinds of methods strengthens technology in this text. On the basis of detailed images from the digital image through the use of an example, a video demonstration of the reality of their role in the final summary of its features, and pointed to its shortcomings. Vc tools for programming to achieve a image processing software, the system used images smooth, median filtering, image Ruihua, pseudo-colour coding these four functions, the need to choose the corresponding image processing functions. Image enhancement system interface more friendly, functional and clear, simple operation.
