Cool suggestions, thanks! Although I don't have multiple images of the same region of one of our surfaces, I will try it out next time we take images. On Wed, Nov 20, 2013 at 1:15 PM, Stéfan van der Walt <stefan@sun.ac.za>wrote:

One last thing to add to this thread. We also have the issue that some images were taken at low resolution, or low magnification. As a result, it becomes quite difficult to ascertain particle distributions. Unto this point, I mostly just made sure to get high quality images, but sometimes this is not possible due to microscope-induced artifacts at long image times. Have you any suggestions or examples for improving low res images of small particles? Otherwise I'll just note the limitations in resolution and leave it at that in my writeup.

If you have multiple images of the same object, you could do super-resolution. If you only have one image, you could try single-frame super-resolution, which is essentially dictionary learning on a large set of similar photos, used to update high-frequency information in the current image.
