I have been given a piece of code by my supervisor but I don't understand the algorithm behind this code to make changes to it.

I know this code using a block and finds contours within the block but can someone please explain to me how it works, essentially giving me procedure? I've added it to my drive - link text

Thanks.

your supervisor is stuck in the 90's.

Sorry if it sounds rude but... why don't you ask your supervisor? Apart from that, the code is definitely not OpenCV3.0, it still uses the old C-api

He's one mean old man @LorenaGdL. Just gave it to me to try and figure it out and make updates to it for HIM and yes it's the C-api because apparently he prefers it.

Then he prefers something that will not work, or at least that will likely cause several problems. You should seriously warn him against using the C-api.

Why not just transform it to C++ API and see the differences, or even the bugs?... I am sure you will understand the algorithm

Possible to give an overview so I can have an idea?

Some guidelines

  1. Start by opening up docs.opencv.org
  2. Now copy paste a cv function - old API and paste that in the search box
  3. Look how the new function is called in the C++ API
  4. Change everything - repeat process and see what other errors occur

Then head back to us!

This code seems to be very similar to this code https://code.google.com/p/easytrack/source/browse/code/grabcut.cpp?spec=svn1&r=1

The name of the file is "grabcut.cpp", but i don't think that this code ralates to the original GrabCut

Anyway, you can try to email the author of "easytrack": https://code.google.com/p/easytrack/
