comment How can I detect a rectangular region of interest in a picture?
I've seen that, but her method fails in the second step on all on my images, the heuristic of taking the largest filled binary region is waaaaay too simplistic to work somewhat generally.

Maybe not, speed is important and we can save a copy of the original to compare against.

Probably center screen, greater area, better edge contrast.

This is a good question, why have people downvoted this? Scraping images is very common tool that people need.

I used to just Import[] a search result page, but this is not possible anymore... Seems like v9 should have integration with google.images api

comment How do I inherit a specific cell option from another style (without copy paste)?
@halirutan Thanks for your answer. I already knew about copying and pasting, that's why I asked this question: I was hoping for something like FontSize -> Inherit["Section"]

comment How to extract metadata from an image of a business card?
@silvia since paper is normally white perhaps looking at histograms would help for object recognition...

comment How to extract metadata from an image of a business card?
@silvia The main complication is the fact that there are typically many many straight lines all over the image, and isolating the "most probably a business card" region is the hardest part!

comment How can I improve Mathematica's resolution on a macbook retina display?
This doesn't work. Retinizer says to uncheck the "Open in low resolution" in the app info in the finder. But the box to uncheck this is greyed out which that means the application does not have HiDPI graphics, oh well :(

I'm trying this on other cards and most of the time the lines are wrong :(

There should be because the app doesn't know this info either and should work on any rectangular document or picture.

I'm trying this with some other images, but I don't know the width and the heights before hand, is there any way around this?

Nice work Silvia! Does anyone know of any free OCR libraries that one could call from mathematica?
