New page splitting approach

Post by Tulon » 16 May 2010, 13:30

Hi everyone,

Remember we were discussing ways to improve page splitting accuracy? The problem was that it's hard to tell a book's spine apart from its vertical edge. So, it seems I found a dead simple way for dealing with this problem: don't try to tell them apart, just cut off everything beyond both of them. On the GUI level this means adding a second cutter to the "Split Pages" stage for single page cases. I've implemented all of that and you can try it in the new build:

Scan Tailor experimental doesn't output 96 DPI images. It's just what your software shows when DPI information is missing. Usually what you get is input DPI times the resolution enhancement factor.

Much better - completely eliminated "page split" errors on the two books I tested. That cuts down considerably on the manual intervention in the "select content" step too. Thanks!

I haven't had the chance to test yet, but this sounds great! Thanks a lot, Tulon.
