21e698053f Initialize background model in background subtraction KNN.
The method does cvCheckPixelBackgroundNP (which reads bgmodel)
before it is ever updated (in cvUpdatePixelBackgroundNP). This
initialization is thus needed to avoid reads of unitialized values.

5372c8b331 Merge pull request #7774 from savuor:openvx_pyrlk
OpenVX optical flow PyrLK wrappers added (#7774)

* wrappers for vx_pyramid added

* initial version of Optical Flow PyrLK wrappers added

* array downloading code simplified

* disabled due to bad accuracy; fixed bugs, e.g. vendor-specific ones

* rewritten for new macro use

9e53f03968 Fixed BackgroundSubstractorMOG2 in opencv_video.
The number of gaussians involved in a mixture is supposed
to be dynamically adjusted. After being increased, the number
of gaussians can't be reduced anymore.

It seems to be a regression as the legacy code
located in modules/legacy/src/bgfg_gaussmix.cpp allows to reduce
such number of gaussians.

86fb9f8409 Modify findTransformECC to support a mask of pixels to consider
Tests of the mask are also included.

This is useful for registering a non-square image against a non-square
template.

This also needs to relax a sanity check as per
