I’ve tried Photoshop and various others but I got blurry contours and I’ve lost the sharpness of the image.
I’ve stepped over a new tool that I’ve found at http://reshade.com which satisfied me completely so I thought that there must me more like me out there, regular people who were amazed by this video but didn’t quite know what to do with it, who just wanted to use the feature in it.

It is essentially a reverse engineering approach, and I would be very surprised if Photoshop's sharpen effect performs this very complex mathematical task. Blind deconvolution is traditionally very slow and very computationally intensive, and could take minutes to perform on just one picture on today's CPUS. But anything is possible :)]]>Aug 2nd 2006 7:08PMhttp://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/http://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/uh, right. it's ineffective to just about every serious photographer who uses it on a daily basis to improve their images. it might be ineffective to some two bit moron who can't take a picture with his terrible quality cell phone camera or to someone expecting a sharp and noise free image taken with some f/5.6 point and shoot inside a museum or at night, but to a real photographer, unsharp mask is an amazing tool.]]>Aug 2nd 2006 7:13PMhttp://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/http://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/Aug 2nd 2006 8:02PMhttp://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/http://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/Aug 2nd 2006 10:02PMhttp://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/http://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/Aug 2nd 2006 10:14PMhttp://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/http://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/
Motion Blur is to blur the image to look like the picture is in motion (or the camera is in motion), haha, not to un-blur it.]]>Aug 2nd 2006 10:38PMhttp://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/http://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/
If this MIT thing is fully automatic and can be done realtime in-camera it's great!

On second thoughts, why can't camera makers include a motion detection sensor in camera (has to be a tweaked gyroscope or something that even detects radial movements... well any sort of movement!) Based on camera shake, the A/D does motion vector sampling every few milliseconds and feeds that data to the on-chip software which now has all the information it needs: shutter speed, aperture, focus & motion vector history. Some complex mathematical treatment, and we should have our blur-free picture.

My 2(0) cents :)

But bumping a camera during a long exposure, while the subject is relatively still, blurs everything in the image more or less equally (save for parallax differences), and this might be a nice addition to the rest of photoshops filters. I don't know if I would pay for it as a plug in.]]>Aug 3rd 2006 1:11AMhttp://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/http://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/Aug 3rd 2006 4:44AMhttp://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/http://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/]]>Aug 3rd 2006 4:48AMhttp://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/http://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/Aug 3rd 2006 5:23AMhttp://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/http://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/

USM is not for correcting blur, it's for sharpening already sharp photos or photos that have been resized.

"Interesting. I've been using this PS tool called FocusMagic to fix motion blurs and has worked wonderfully for me. Contrary to the software's name, it does not fix *focus* but actually the *motion* blurs. But it needs some manual fiddling with vector -direction and degree (pixels) of blur and doesn't work on complex ones, you know like lot of shake or circular movements."

Focus Magic can work with both out of focus blur and motion blur, although I rarely have good luck fixing motion blur. Photoshop's new smart sharpen has technology that works the same way as Focus Magic. Except it's a lot faster and allows fractional radii. For instance, in Focus Magic, you can choose a radius of 1 or 2 or 3. In Smart Sharpen you could use .6 or 1.3.]]>Aug 3rd 2006 8:54AMhttp://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/http://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/
Here is a simple explanation of how the unsharp mask works:

Nope. Who told you that? SS uses intelligent comparison of gaussian vs original versions with variable radii. I'm a developer myself so although I can't reveal much here,the exact focus/motion blur feature u are talking about should be there in Adobe Lightroom final. Until that time, do test drive the beta 3 mate!]]>Aug 3rd 2006 10:29AMhttp://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/http://www.engadget.com/2006/08/02/researchers-develop-algorithm-to-combat-photo-blur/
