毕业设计（论文）-Visual C 图像特效输出的设计与实现【毕业设计】 图像特效输出的设计与实现 摘要 随着计算机电子技术和计算机技术的发展数字图像处理进入高速发展时期由于某些特殊原因一些图像的效果不能够达到人们的要求因此需要对图像做一些再加工即利用计算机进行特殊的处理称为图像特效处理随着对数字图像处理研究的深入图像特效处理的应用越来越广泛其发展状况也受到了人们的广泛关注 本文针对目前图像特效处理的需求主要研究几种基本的数字图像处理算法以达到人们所期望得到的各种不同的效果并在基于Windows系统的Visual C60集成开发环境下使用VC编码实现这些算法在点运算处理中介绍了灰度直方图灰度分布均衡化灰度化处理灰度线性变换和二值化处理几种算法算法设计原理是将输入像素点的灰度值通过算法实现改变其相应输出点的灰度值在几何变换中介绍了图像的平移图像的缩放和图像的镜像变换几种算法这些算法主要是根据某种矩阵运算来写的有其固定的数学计算方法在图像的增强中介绍了图形的平滑和图像的锐化算法其算法的设计原理是根据一个固定小区域的几个像素灰度值设置某个像素的灰度值通常有其固定模板在图像特效处理中介绍了图像反色图像曝光浮雕处理霓虹处理和马赛克几种算法这些算法主要是针对真彩色图像通过固定的公式计算改变其像素的RGB的分量值从而改变像素的颜色达到不同的颜色变换效果 本文具体给出了这些算法的设计思想及算法描述并通过程序实现最后将其效果图与原始图像进行了比较 关键词　数字图像处理图像算法图像特效处理Visual C60 Abstract With the development of the computer electronics and computer technology digital image processing into the high-speed development period For some special reasons the effect of a number of images can not be met and thus the need for images to do some further processing namely the use of special computer processing known as image processing effects With the digital image processing to study in depth image effects processing of the application of more and more widely and its development has been the peoples attention In this paper the image effects to deal with the current demand for basic research in several digital image processing algorithms in order to achieve what people expect different results Processing of the points on the histogram a balanced distribution of gray gray-scale processing gray-linear transformation and binarization processing of several algorithms Algorithm design principle is to enter the gray value of pixels through the algorithm to change its output points corresponding gray value In the geometric transformation the introduced image translation scaling and image of the mirror image transform several algorithms are mainly based on a matrix calculation to write has its fixed mathematical calculation Enhancement of the image on the smooth graphics and image sharpening
