Algorithm on Extracting High-Resolution Image from Low-Resolution Image Sequence
Shao Ling, Ibm China · Dianzi xuebao · 2002
Extracting a high resolution image form a low resolution image sequence with displacement solves the image super resolution problem which is ill posed to one frame based interpolation.However it is indispensable to store all low resolution images for traditional multi frame based algorithm which can not be implemented in real time.In this paper,we propose a multi-frame based recursive iteration algorithm which can achieve super resolution result as good as traditional method but with less memory consumption.The proof of convergence and efficiency of this algorithm is also addressed.Computer simulation gives the result matching with theoretical analysis.
