摘要
利用VC6.0设计了一个数字图像压缩平台.数字压缩平台能对8位灰度图像或24位真彩图像做基于几何不变量压缩、JPEG压缩和分形压缩处理,并能以对话框的形式给出图像的压缩比(CR)和峰值信噪比(PSNR),同时能将原图像和解压后的图像显示在不同的窗口中,供用户进行图像压缩效果的分析和性能比较使用.
A platform for digital image compression was designed using VC6.0. The platform can compress 8-bit grayscale images or 24-bit true color images by compression based on moment invariants, JPEG compression and fractal compression, give compression ratio （CR） and peak signal to noise ratio （PSNR） in dialog box, and display the original image and retrieval images in different windows, which is convenient to analyse results and compare compression performance.
