Hi, Web pages are quite different to document images due to their very low resolution and anti-aliasing effects. You can try Voronoi segmentation (of course after binarizing the image) as outlined in my post that you referred to. If you are using OCRopus 0.4, you can put that code in the commands folder and run scons at the top-level. You should get an executable for the Voronoi segmentation module.
