Research on Noise Influence upon Inversion Analysis for Enhancement of CCD Resolution
Ling Wang, Huajun Feng · Jiliang xuebao · 2004
Inversion analysis is one of the methods for the enhancement of CCD resolution. But the random noise added to low resolution images will have unpredictable influence over the synthesized high-resolution images. The principle of inversion analysis is introduced. Then, the influence mechanism of noise is discussed and a noise influence evaluation function is put forward for the digital analysis of noise influence. Finally, the law that random Gaussian white noise influencing synthesized images is found through simulation examples based on the noise influence evaluation function.
