Untitled. Deconvolution. To increase resolution of the images, the best way is the deconvolution.
Iris includes several deconvolution algorithms, for example the Richardson-Lucy algorithm, known to be used for the Hubble Space Telescope.

In mathematics, deconvolution is an algorithm-based process used to reverse the effects of convolution on recorded data. The concept of deconvolution is widely used in the techniques of signal processing and image processing.
Because these techniques are in turn widely used in many scientific and engineering disciplines, deconvolution finds many applications. In general, the object of deconvolution is to find the solution of a convolution equation of the form: Usually, h is some recorded signal, and ƒ is some signal that we wish to recover, but has been convolved with some other signal g before we recorded it. The function g might represent the transfer function of an instrument or a driving force that was applied to a physical system.
Removing camera shake from a single image. Abstract Camera shake during exposure leads to objectionable image blur and ruins many photographs.
Conventional blind deconvolution methods typically assume frequency-domain constraints on images, or overly simplified parametric forms for the motion path during camera shake. Real camera motions can follow convoluted paths, and a spatial domain prior can better maintain visually salient image characteristics. We introduce a method to remove the effects of camera shake from seriously blurred images. The method assumes a uniform camera blur over the image and negligible in-plane camera rotation.

Photo-deblurring Research Debuts at Siggraph Conference - Emerging Technology - News - DigitalCamerainfo.com. August 02, 2006 By Karen M. Cheung A Massachusetts Institute of Technology and University of Toronto research team debuted photo-deblurring technology at yesterday’s 33rd Annual Siggraph Conference in Boston, MA. In a seminar entitled "Removing Camera Shake from a Single Photograph," the MIT – U of Toronto research team presented an algorithm to correct high-level blurs at the world’s largest electronic and computer graphics conference today, which hosts "the best and most senior minds in technological innovation," according to Siggraph spokesperson Brian Ban. The anti-blurring mathematical model can only correct a particular type of blur caused by hand motion.

Researchers take the blur out of shaky photos. Researchers have unveiled an image-processing technique that shows promise for fixing images spoiled by camera shake.
The technique is based on an algorithm that deduces the path that a wobbling camera took when a photo was shot, then uses that path to reverse much of the resultant blurring. The method isn't a miracle cure, but researchers at the Massachusetts Institute of Technology and the University of Toronto have used it to significantly help a wide variety of sample images. One example shows a bird with black, white and rust-colored feathers, blurred to the point where its legs are barely discernable. After processing, it's possible to see not just the legs, but also a dark patch around its eyes, white patterning amid the black feathers and other details. The technique, which takes 10 to 15 minutes for typical images, uses a statistical property that describes transitions from light to dark in the photo, Fergus said. Rob Fergus - HomePage.
