[edit] Image as superresolution

Hello,

Does that Image really display superresolution? As I understood it, super-resolution was when the image was able to identify features smaller than the diameter (radius?) of the Airy disc used for imaging. I thought super-resolution required physical analyses such as time-reversal for active signals or negative refractive index metamaterials. Either that or deconvolution techniques such as the Lucy-Richardson algorithm. It seems to me that the image is merely displaying supersampling or something akin to this, and thus doesn't belong here. Please comment, as I am unsure about this to some extent.

Futhermore papers by people such as John Pendry and others in this area may help us here User A1 —Preceding unsigned comment added by User A1 (talk • contribs) 07:49, 31 August 2007 (UTC)

It increases the resolution beyond what the camera is capable of, so I would imagine it's superresolution in at least a loose sense. All I know about the algorithm is that it depends on knowledge of the camera model. (I got a free copy of the software by taking test images with my camera for them to process and put in their libraries.)

By all means upload something else if you know of a better example. — Omegatron 22:55, 31 August 2007 (UTC)

I read the IEEE paper in the article, I understand where my confusion comes along. There are two types of super-resolution in the literature. One where the CCD is considered to be the limiting factor for resolution, and as such multiple images can be used to provide an increased resolution estimate, the other is where you have diffraction limiting behaviour, which is a different kettle of fish entirely.... I will try to improve my understanding here and see what i can do to improve the article. User A1 00:27, 1 September 2007 (UTC)
