Fix blurry photos (try)

Post by myspacee »

Hello,
while searching a valid solution to fix blurry images, i found a software that use IM; I don't know if legally.
(blurity - https://www.blurity.com/)

Try DEMO, and find this software user friendly.
Can't figure how it works but maybe someone can find which parameters it use

in alternative can you bring me in right direction to try to fix blurry images ?

thank you,
m.

It depends on what has caused the blur. IM has the tools to reduce the effects of cheap lenses or slightly out of focus. Blurity is for a more complex problem, where the camera has moved (maybe in a non-linear manner) during exposure.

Looking at the website, the software analyses a photo to determine the camera motion, for example by picking out specular highlights. Or the user can manually isolate an example of the motion. From this, the program builds a deconvolution matrix, and applies it. See, for example, http://en.wikipedia.org/wiki/Richardson ... onvolution

I suspect IM contains most of the low-level tools required to do this processing. But it would need work to put it all together. Locking Anthony and Fred in a room together for a week would probably do it.

How do you know that it uses Imagemagick? I do not see that indicated anywhere?

Some of my scripts can do some uniform straight line motion blur or pure lens defocus. See my scripts cameradeblur, fftdeconvol, and cepstrum. The latter is used to estimate the motion blur direction and length or the defocus diameter.

Also see http://www.fmwconcepts.com/imagemagick/ ... plications

The blurity application is doing a lot more if it can deal with non-linear motion blur.

Hi fmw,
Try to open installation directory, you will find IM files. Report here to allow IM to check the correct use.

Already try to use your script, have some difficult to build right 'mask' and then defocus. My inexperience.

Thank you for all,
M.
