* run length morphology

* remove unused code, avoid warnings for undefined functions

* handle empty input in getBoundingRectangle correctly, remove unused operations

* changes according to code review

* fix #1665 ChAruco board topology (nearestMarkerIdx) is sensitive to scale

* Some bugs in deriche and paillou filter

* Cv_Assert to CV_CheckType

enables an ordered chain of full-screen post processing effects

In some case, Discrete Fourier Transform in computeSaliencyImpl() returns
magnitude matrix which contains zero values.
Then, log() returns -inf values and normalization with blur() returns -nan.
When computeBinaryMap() is called double free or corruption exception occurs
because kmeans() fails to compute distance.

* update structured_edge_detection 

update structured_edge_detection to read models from updated p. dollar toolbox

* Update structured_edge_detection.cpp

* Update structured_edge_detection.cpp

casting size_t to int

for this
- move Params struct out of class
- use static create instead of pimpl
- allow demo to be compiled without VIZ

* KinFu demo: added support for live demo, some bugs fixed

* minor fixes

* Kinect2 workarounds and defaults added

Bug fixes: using mask with BinaryDescriptor  (#1652)

* Bug fixes: erasing an element from std::vector should not move iterator forward

* Bug fixes: add a NULL checking

* Remove the appoggio matrix generation, which is useless
