摘要
首先分析小波双线性插值的图像放大算法优缺点,然后根据小波分解各部分之间也具有相似性提出了一种改善的被小波变换修正的双线性插值算法,其仿真结果显示放大后图像在细节丰富程度上不如前者,但视觉效果上改善明显。
This paper first analyses advantages and disadvantages of image zooming algorithm based on wavelet transform and bilinear interpolation.Then according to the similarity of wavelet component,it gives a improved bilinear interpolation algorithm modified by wavelet transform,which simulation result reveal visual effects of zoomed image is improved greatly,although its details is less abundant than former.
