Ever taken a digital photograph and then found out you had missed the fine details that made the scene so impressive visually? Applying a Photoshop sharpen filter may make the photo appear sharper, but such filters are lossy – they actually reduce the amount of fine detail in the image. Until recently, there was very little you could do to improve the image after the shot. Researchers at the Weizmann Institute of Science have now developed a super-resolution process which pulls unseen details from the nooks and crannies of a single digital photograph. Their process can capture true detail which cannot be seen in the original image – the next “killer app”?
