Given an image, I'd like to extract all groups of adjacent non-white [1] pixels by their rectangular bounding boxes:

Diagonally neighboring pixels ( ) may or may not count as adjacent.

Can you give me a few pointers?

  1. Change your platform toolset to Visual Studio 2010. (Configuration Properties -> General -> Platform Toolset)

  2. Make sure you're using the binaries in opencv\build\x{86|64}\vc10

The binaries in vc10 were built with VS 2010 and are incompatible with VS 2012. OpenVC doesn't ship with a native VS 2012 build yet.
