3107f5df76 facedetect: Fix compiler warning with clang 3.8
Use namespace only after it was actually defined by a header.

044ed50190 opencv/facedetect: fix the build with opencv 3.1.0
- add using namespace std; for std::vector
    - use the cpp header imgproc.hpp file for the cv::ellipse function instead of
      the C header
    - Mat no longer takes IplImage in it's constructors, use the cvarrtomat()
      function instead.

    Fixes a couple of build errors:

4e1aba0923 opencv: segmentation: Ported to OpenCV version 3.1
Add namespace bgsegm, replacement functions and Template class for new
OpenCV versions because these functions have been removed. cvarrToMat() is
added because it is compatible with all versions of OpenCV and the use of
class Mat constructor is eliminated, it is also deprecated in 3.X versions.

Use the namespace cv because some functions are called many times.

This patch keeps compatibility with 2.4

36e83661ec opencv: fix cvlaplace
cvlaplace was also affected by the silent change in OpenCV API, same as
cvsobel. It hasn't been working for a while. It would return a plain black
image. This commit updates the usage of cvLaplace by using cvCvtColor to
create the grayscale intermediate image to process. This also means there
is no need anymore to use GstBaseTransform's transform_caps, since the pads
are RGB.
