插值算法在图像缩放中的评估研究

Assessment Study of Interpolation Algorithm for Image Scaling

图像缩放是数字图像处理的一个基本内容。介绍了图像处理中最常用的3种插值算法:最邻近插值法、双线性插值法、双立方插值法。通过应用不同的插值法对图像进行缩放,比较实验结果,从而验证双立方插值法效果较好。

The image scaling is an essential element of digital image processing, this article describes the most commonly used in image processing of three interpolation algorithms： nearest-neighbor interpolation, bilinear interpolation, bicubic interpolation. Zoom the image by applying different interpolation to compare experimental results to verify that the bicubic interpolation method is better.
