Re: simply / bulid in few hours good quality book scanner

It is heavy book manipulations. There are consequences : - This cannot be a fast process. - the book will move every shot. you must have proper positionning marks or visual control of the shots so that to perform corrections. - many operations on the book. I would consider this for old book, as it m...

Re: Waifu2x could help us in any way?

Really nice.

Beside the image lens capability, the smooth line feature capability may be of use when dealing with character rasterization.

In the same vein, I wonder if somebody already explored the new OpenCV 3 functionalities. The python port is just out, have not time yet to test this.

Re: A review of the YASW software written by tibob

A very good soft, the best so far to prepare images for archive.org.
I appreciated a lot the control on the output size and the dewarping which provided good results even on badly distorted image.
I hope to see more update.

Re: Bitonal conversion using Photoshop (Gimp & Imagemagic...

Nothing changes : As soon as I put the command into single or double escaped bracket, I got the function errors. Can you post a command that works on your setting. Actually with all the failures, I am not even sure of what should be code. If I remove the enclosing non-escaped double quotes, I get th...

Re: Bitonal conversion using Photoshop (Gimp & Imagemagic...

Double quotes around the parentheses result in 'illegal function'. Simple quote and quadruple quotes results in 'batch command executed successfully' but nothing produced. Writing 'C:\Documents and Settings\P0957\.gimp-2.8\pluginrc' Starting extension: 'extension-script-fu' No batch interpreter spec...
