Thirdly , the new method and nearest - neighbor method , single linear interpolation , bilinear interpolation were coded by vc + + , and a mfc application , bmpinterpolation , was achieved . many kinds of examples were tested using bmpinterpolation , including single color images and true color images ( 24bits ) , photos and images after 3d rendering by 3dmax . the comparison between new method and the others indicates that the new method can not only get higher quality of images but also match the requirement of procedure speed 用该程序可以实现了对单幅位图文件的读取和插值放大,通过单色和彩色图像、照片图像、三维渲染图像等放大处理算例的检验,说明了本文的方法和程序是成功有效的,新算法明显优于几种简单插值放大方法的轮廓清晰度,且具有很好的快速性,兼顾了自动立体镜三维显示的快速性和清晰度要求。
The requirements for image processing in auto - stereo - display , high image resolution and fast procedure speed , were deduced from such mechanism . the interpolation based on the refinement of shape - profiles was adopted for image magnifications as fast as possible , after analysing main advanced methods of image magnifications . secondly , a new algorithm of smoothness shape - profiles was studied by analogy the thermal diffusion 总结了当前已有的各类主要插值放大算法,根据自动立体镜三维显示需要兼顾快速性和清晰度的要求,选择了基于图像轮廓边缘处理类型的放大算法作为本研究中放大图像的技术思路,以保持对图像视觉效果至关重要的图像轮廓信息。
