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,以达到人们所期待得到的各种不同的效果。并在基于Windows系统的Visual C++6.0集成开发环境下,生成BMP位图文件并对其进行读取,使用VC编码实现这些算法。编写程序在BMP位图文件中画出各种图像,例如:三角型,圆,正弦函数图。在点运算处理中介绍了灰度化处理,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。在图像增强中,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。
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。
(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 result. And Windows-based system, Visual C++6.0 integrated development environment to generate BMP bitmap file and read them using VC coding to implement these algorithms. Write a program to draw a variety of graphics in BMP bitmap file, example: triangle, circle, sine function diagram. Point arithmetic processing grayscale processing, algorithm design principle is the value of the input pixel gray value of the corresponding output point algorithm change. Enhancement of the image on the smooth graphics and image sharpening algorithm. The design principle of the algorithm is based on a fixed number of small regions of a pixel value of gray-scale pixel value, usually a fixed template.
In this paper, given the specific design of these algorithms and the algorithm description, and program . Finally, the effect o)
