Jigsaw puzzle solver

I have a huge (6000 piecese) jigsaw puzzle I'm not able to finish, so I was thinking about getting some help from my PC. 8) I was thinking about splitting the sample image: http://img4.imageshack.us/img4/6808/originalez.jpg into a grid, based on pieces size: http://img220.imageshack.us/img220/7235/g...

Thanks, but I do not need to clean the background, I want to extract text areas from a scanned page, and I need the script to find the areas by itself.

Re: How to crop out multiple pictures on a single file?

I bring up this old thread to ask if, in last two years, something new came around about image segmentation. I'd like to be able to extract all words from an image, to use each single image as if it was a character in a text, thus allowing text reflow even in scanned pages. Example image: http://img...

Re: ebook distortion

The one number on the first to specify the 'order' for the polynomial Eg: 3 10,10 0,0 10,5 0,10 and so on I guess you mean "add a '3' as first line". I didn't get why you were talking about one line while meaning one number (as I'm specifying all parameters on a single line). But I alread...

Re: ebook distortion

All pages would have same distortion, so once I find the algorithm for first pages, it will be ok for all of them. Gwenview (Linux viewer) displayed a thumbnail image of your book in which I saw it being held between two hands standing on a table. I was thinking that it would be difficult to make t...

Re: ebook distortion

Out of curiosity I tried to remove the distortion using Hugin as per the tutorial http://hugin.sourceforge.net/tutorials/perspective/en.shtml I'm sorry but you got a very poor result! Characters are even more distorted! (some ones are bigger than others) Somewhat successful. It might have been bett...
