| 摘 要： | 本文研究了一种空域中的图像分解技术，进而利用改种分解方法，探讨了图像插值算法。本文提出的图像分解方法的主要思想是：利用类型确定的滤波器（如低通）对原始图像滤波，将图像分解为高频和低频两部分，并对分解得到的低频或高频成分进行处理，图像可分解成不同频率分量的图层之和，进而在各个图层一L进行相应的插值处理，最后利用逆变换得到最终的结果。

| Abstract: | In this paper, a spatial decomposition method based on filtering technique is pro- posed and then image interpolation tasks are discussed based on this newly decomposition method. The main idea of this method covers following components, decompose an image based on a filter which is given in advance into high and low frequency components, repeat the decomposition procedure for the low-frequency or high frequency components continu- ously, and then the original image is divided into different frequency components of the image layers,then the corresponding processing is carried out on each of these layers, at last, the final result is obtained by the inverse decomposition. |
