针对现有彩色图像插值算法的实时性及可靠性不能兼备的问题,提出了一种高效的实时彩色图像缩放算法,算法基于Lanczos核生成可应用于整个目标图像的核查找表,并且目标图像所有像素的插值仅涉及定点小数运算,计算复杂度低;同时算法采取了优化的光栅扫描方法,内存需求低、效率高。实验结果表明,该算法不仅获得了较好的图像质量,而且计算复杂度远低于经典的图像缩放算法,能有效实现彩色图像甚至彩色视频的任意倍数实时缩放。
In order to improve the timeliness and reliability of color image scaling algorithms
a high effective real-time color image scaling algorithm was proposed
which first generated the kernel look up table that could be used for whole target image based on Lanczos kernel
and interpolation of all target image pixels had only fixed point operation which had low computational complexity.Meanwhile
an optimized method for rasterizing pixels of target image was proposed
which needed little memory space but embraced high efficiency of memory utilization.The experiment results show that the proposed algorithm achieves good image quality
and the computational complexity is far more less than classic image scaling algorithms.So the proposed algorithm can effectively implement real-time resizing of color images and color videos in any scaling factors.
