Error when building seg_tree_sample

[mkaze]

After installing all the required dependencies, I tried to build seg_tree_sample; but unfortunately when I entered sudo make -j4, it gave me the following errors:

I am using Ubuntu 14.04, OpenCV 3.0.0 and ffmpeg 2.8. I didn't encounter any errors during installation of OpenCV and ffmpeg (apart from some warnings during installation of ffmpeg). I couldn't figure out what causes this problem.

OpenCV 3.0 changed a bunch functions and modules, e.g. putText, ellipse went to imgproc module. We haven't updated it yet, but feel free to send us a pull request.
