resolves: #1157

fixed typo

replaces Mat& to Input/OutputArray in public methods.

small fix.

small fixes

* Fixed bugs after dnn refactoring. Added new tests for layers

* Fixed torch tests

* the first commit in the merged dnn: convert some public API from Blob's to Mat's

* temporarily or permantently removed OpenCL optimizations, which are not always stable nor usually very efficient; we'll likely use Halide instead

* got rid of Blob and BlobShape completely; use cv::Mat and std::vector<int> instead

* fixed a few compile errors

* got rid of separate .hpp files with layer declarations; instead, put everything into the respective .cpp files

* normalized all the layers' constructors; we concentrate on loading deep networks layers from files instead of constructing them from scratch, so we retained only SomeLayer::SomeLayer(const LayerParams& params); constructors

* fixed sample compilation

* suppress doxygen warnings

* trying to fix python bindings generation for DNN module

* temporarily disable python bindings while we refactor the module

* fix win32/win64 compile errors; remove trailing whitespaces

* fix win32/win64 compile errors; remove trailing whitespaces

Correcting bgsegm module descriptions.  (#493)

* Correcting bgsegm module descriptions. The algorithm implementation doesn't have multi target tracking as mentioned in original paper. it only does foreground/background segmentation.

* Removing opencv_ from heading

Removing opencv_ from description

fixing matlab wrapping

new corner refinement method :: using the contour-lines (#973)

* doCornerRefinement to CornerRefinementMethod :: detected contours points are used to detect the corners

* some little corrections

* samples edited

* documented :)

* tabs corrected

* Docu corrections

* refinement for all candidates

* refinement for all candidates :: copy paste error corrected

* comment

aruco: make public the getBoardObjectAndImagePoints function (#1108)

* Made the private static getBoardObjectAndImagePoints function public to be used for calibration.

* Switched the arguments detectedIds and detectedCorners, and objPoints and imgPoints on getBoardObjectandImagePoints function for consistency with calibrateCamera and calibrateCameraAruco functions.

* Added the flag CV_EXPORTS_W to the getBoardObjectAndImagePoints function.
