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. For example, download the file BLUR1.ZIP and decompress it in your working directory. Deconvolution

Deconvolution 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.
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. Removing camera shake from a single image
Recover Detail and Sharpen Your Blurred Photos
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.
Ernst Lippe is the author of "refocus". Here is an excerpt from the author's description. Refocus is a plug-in for the Gimp (the GNU Image Manipulation Program). This plug-in attempts to "refocus" the image, using a technique called FIR Wiener filtering. The traditional technique for sharpening images is to use unsharp masking.

Downloading and running UnBlur for simple images This page describes how to download and run the UnBlur program for simple images. It is presented here in a question and answer format. Downloading and running UnBlur for simple images - John Costella
UnBlur — image deblurring software UPDATE: 12 January 2012: I have recompiled the executables in quick_ub.zip so that they run under modern versions of Windows. Thanks to Jon Edlund for pointing out that the versions compiled in 2003 no longer worked! UnBlur - image deblurring software - John Costella

More Results Training Data Single Image 3D Reconstruction
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.

Once again, Adobe is about to change the wold of photography forever. During the company’s MAX 2011 conference, which took place last week in Los Angeles, California, Adobe gave a sneak peak of a new Photoshop filter that will allow users to unblur their shaky photographs. The new feature, which is still in development, was revealed to the public in a YouTube video posted to Reddit.com. In the video, a presenter (whose name we cannot confirm) showcases the functionality of the unblur filter. As the presenter explains, the filter analyzes the form of the blurred photograph to figure out which direction the camera moved when the shutter was open, thus creating the out-of-focus image. An algorithm in the software then makes a highly educated guess about how the photo should look if the camera had not moved. Adobe unveils amazing 'unblur' feature for Photoshop [video]
