So I have Image like this

CG generated bathroom

I want to get something like this (I hevent drawn all lines I want but I hope you can get my idea)

Black & White CG generated bathroom with some red lines between tiles

I want to use SURF ( (Speeded Up Robust Features) is a robust image descriptor, first presented by Herbert Bay et al. in 2006 ) or something that is based on sums of 2D Haar wavelet responses and makes an efficient use of integral images for finding all straight lines on image. I want to get relative to picture pixel coords start and end points of lines.

So on this picture to find all lines between tiles and thouse 2 black lines on top.

Is there any such Code Example (with lines search capability) to start from?

I love C and C++ but any other readable code will probably work for me=)
