Re: Restore Text within Image

If this is the best source you have, i guess it is impossible because there are 3 problems at once,
- JPEG-artefact
- noise
- blurry

if you have a bigger resolution maybe there is a way.
What is the original size? (in pixel)

Re: Restore Text within Image

hi,
just my 2 cents worth... just a novice really
but i don't think ps can do it...at least not that severe bluring

main problem i see is that a lot of motion blur in both image although 2nd one is much worse than the first.

i have tried that little feature in cs5 for motion blur but didn't work well with your image.....

my own suggestion is maybe download the demo version of focus magic... heard a lot of good comments about it addressing motion blur, the only thing was what avail only works in photoshop 32 bit...

Re: Restore Text within Image

I tried the two with focus magic, no chance.
I personally use Image Analyser for this task, it is free and has a lot of powerful features (including motion blur deconvolution, but with more possible tweaks).

The problem of this image is it also downscaled, so without the original image there is no way. The second image which looks more worse has suprisingly a better recovery chance.

or maybe you could send a request to the CSI-Team ;-)

Re: Restore Text within Image

I've had a go with a deblurring prototype by Sunghyun Cho that achieved this result attached. I couldn't get it to work on the submitted text as like smaster said the noise and jpeg artefacts are a problem. Also there are four perameters that control the output and they have to be accurate or else the result is bad and as there's no user interface it's pure guesswork to get them right.

The two developers are currently in partnership with Adobe and if all goes well it may be incorporated into the next release of PhotoShop.

Heres a great video from an Adobe Max 2011 exhibition http://www.youtube.com/watch?v=Q10kw...eature=related Adobe's Jue Wang wows the audience with a sneek peek and talks further about the process behind the deblurring.

You can get the executable to play around with by following the first link.

Hello,
that is a real good one, especially the auto-function thx for sharing,
the best i have seen so far for motion deblurring.
Does Sunghyun Cho send the exe to everyone?
(I like to try it also)

Re: Restore Text within Image

Yes it's available to anyone. Unpack the zip file and in the examples folder change the file named run_deblur.ba_ to run_deblur.bat and in the bin folder change fast_deblur.ex_ to fast_deblur.exe. Double click the .bat file to start the deblurring process on the 4 images supplied. The .bat file contains the settings for each of the 4 picture jobs. You can add your own jobs too.

Re: Restore Text within Image

Hi smaster the .bat file should read like this:
..\bin\fast_deblur.exe boy_statue.jpg boy_statue_out.jpg 49 47 0.5 0.0005
..\bin\fast_deblur.exe fishes.jpg fishes_out.jpg 61 43 0.5 0.0005
..\bin\fast_deblur.exe hanzi.jpg hanzi_out.jpg 33 33 0.5 0.001
..\bin\fast_deblur.exe harubang.jpg harubang_out.jpg 35 49 0.5 0.0005
..\bin\fast_deblur.exe summerhouse.jpg summerhouse_out.jpg 65 93 0.5 0.0002
pause

Then if you double click it it should do the five images provided just fine.
Those params only work well for their respective image. If you want to add your own such as
..\bin\fast_deblur.exe myPic.jpg myPic.jpg 61 43 0.5 0.0005
Then you'll have to try changing the params by trial and error. The README.txt shows how best to set them.

Re: Restore Text within Image

Thank you rco.
I tried it, and the algorithm isn't perfect like i thought, In full screen view there are some color problems visible like smear or blooming.

I have found another good scientist, look at his publications and software:

I dont have the time this week to do, but i guess it is also great (i read the pdf files)

greetings
