迭代滤波插值算法

In the paper , demosaicking approach based on iterative filter is introduced .The proposed demosaicking method consist s of two successive steps : The demosaicking approach make use of new edge-sensing method firstly getting initial image ,then do iterative filter for initial image. Experimental results indicate that the image gets improved by filtering。Compared with common algorithm image’s PSNR can improve about 3dB and have low computational complexity.
