Image Interpolation Arithmetic Based on the Filtering Decomposition
Yan Wen Tian · Journal of Wuhan Institute of Shipbuilding Technology · 2009
In this paper,a spatial decomposition method based on filtering technique is proposed 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 continuously,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.
