High Resolution Reconstruction Of Digital Video With Non-Global Rigid Body Motion, Timothy Tuinstra, Russell Hardie

Russell C. Hardie

Many imaging systems utilize detector arrays that are not sufficiently dense to sample the scene according to the Nyquist criterion. As a result of this undersampling, some of the higher spatial frequencies admitted by the optics are aliased to lower frequency representations in the sampled image. This creates undesirable artifacts that decrease the utility of the imagery. Furthermore, the blurring effects of the optics and the finite detector size also degrade the image quality. Several approaches for obtaining a higher sampling rate have been suggested in the literature such as controlled and uncontrolled microscanning or from natural camera platform motion …
