基于VC++ 的图像处理程序设计与开发

摘要

数字图像处理是指将图像信号转换成数字信号并利用计算机对其进行处理的过程。图像处理的主要任务是，将原图像中的像素灰度分布进行某种变换，以改变图像的信息表现方式（如加深对比度），从而满足特殊的显示（如平面处理）与应用需要。灰度变换是指按照某种算法改变各个像素的灰度值的变换方式。对比度是指投影图像最亮和最暗之间的区域之间的比率，比值越大，从黑到白的渐变层次就越多，从而色彩表现越丰富。图像的单色化就是指将一幅图像中所有像素颜色的R、G 、B值按一定的比例重新计算得到一个新的像素值，从而应用于整幅图像，使其都为一种颜色。

Abstract

Digital image processing refers to the image signals into digital signals and processed by computer process. The main task of image processing is that the original image pixel gray-scale distribution of a transformation to change the performance of image information (such as better contrast), to meet the special display (such as the flat to deal with) and the application needs. Gray-scale transformation algorithm refers to a change in accordance with the gray value of each pixel of the transformation.Contrast refers to the brightest image projection and the dark regions between the ratio the greater the ratio, from black to white gradient, the more levels, so the performance of the more rich colors. Monochromatic images of an image refers to the color of all pixels of the R, G, B by a certain proportion of the value of re-calculate a new pixel value, which applies to the entire image to have a color.
