Is there an application that would batch convert photos made from some angle to frontal ones? I know ShiftN does batch perspective correction, but I would like to automatically convert some photos of buildings that have visible lines and were made from like 70' angle to frontal textures.

Why does the batch perspective correction not work for your needs? Also, keep in mind that the actual captured information is still going to look weird unless the building is perfectly flat as you are actually capturing the image at an angle which means that any 3d geometry will cause odd stretching in the corrected image. –  AJ Henderson Aug 23 '13 at 13:56

Perspective correction can be performed in any direction and will work on the sample image you showed. Lightroom 5 has an automatic "upright" tool which may be useful to speed up the process, but it doesn't always get it right. –  Szabolcs Aug 23 '13 at 14:14

@FlashThunder What's your application? For photography, with an angle even greater than in your sample photo, a fully perspective corrected version is going to look very weird. If the application is more like google street view (and you have a huge number of images), perhaps you can try to roll your own algorithm (using a package like Mathematica/MATLAB) and you'll find more expertise on dsp.stackexchange.com. You'd be starting with a Hough transform to detect lines. –  Szabolcs Aug 23 '13 at 14:46

-1 for no sample image. The process clearly works with most images and as it stands the question is for everyone not reproducible. Upvote once sample is added... –  Unapiedra Aug 23 '13 at 15:49
