| 摘 要： | 该文提出了一种视频图像整数倍放大的实时插值方案一改进的像素填充插值法，给出了其基本原理及软、硬件实现方法.与重复插值法、线性插值法、像素填充插值法和小波放大法等进行了比较，并给出了放大后图像的主观和客观评价。结果表明改进的像素填充插值法的效果明显优于其他实时放大方法，且其硬件实现并不复杂，可用于视频图像实时放大的软、硬件设计。

| Abstract: | A kind of interpolator, called the modified pixel-filled interpolator, is advanced for images enlarged the same integer times in lines as that in columns. The principle and the implement method in software and hardware of the interpolator are given. Comparing with the nearest neighbor interpolator, the bilinear interpolator, the pixel-exchanged-interpolator and the wavelet-based zooming methods, the effects of enlarged images with this interpolator are better according to the subjective and objective evaluation to the enlarged images. Its implementation in software and hardware is easy, and can be applied to all kinds of image zooming. |
