Library to manipulate images ?

[felix]

Hi,

I'm looking to a library that facilite the job in manipulate images.

The library should make manipulation in at last one of this formats:

- Jpeg
- Png
- Tiff

I need a library that allow me to:

- Recoganize objects in a picture (for example, suppose a picture with a letters A, B and C, I need it recoganize A, B and C as a object).

- Cut this object with a pre-defined border size (height and width) and save in a different buffer. To make all this object the same size. ;)

- Tilt, curve, the image (object), etc.

- Clean pictures, for example retrive dirt, risks without connection, etc. This kind of think we make when we scan very old pictures with bad quality.

Someone know some magic library that do it or similar ? ;)

Thks a lot.

Only image library I know is Imagemagick, http://www.imagemagick.org. It has a very liberal license and it's also cross-platform. It's most likely won't to the character detection, but I'd be surprised if you find an image lib which does it. It isn't very easy to recognize fonts and what not from images. Search about "Optical Character Recognition", or OCR to get more info about that. This seems a good starting point:

This one seems to be actively used and may be useful (latest update Februari):

http://www.gnu.org/software/ocrad/ocrad.html

So you'll need both an image library and some OCR.

Hi I3839,

Excellent links, very useful!! I already was using OCR, but the libgocrm and it wasn't give me the results I went, this link with a lot of librarys to use OCR is wonderful!! And this ImageMagick appear to be very useful to me too!!
