[cudalegacy] Possibly fix assertion to use something more meaningful `totalDetections <= totalMaxDetections`

dereferencing type-punned pointer will break strict-aliasing rules

* Add learning-based super-resolution module

Adds the module plus loading classes for SR data

Complete with docs, tutorials and tests.

* Fix typo

* Small commit to restart buildbot

* Change refs from arXiv to official

* Remove video string

* dnn_superres: update perf test code

* dnn_superres: test fixup

waldboost_detector train: avoid failed asserts while training by exiting early

* Avoids a failed assert which crashes training

* xobjdetect: improve waldboost messages

If 'lambda <= 0' or 'kappa <= 1.0', the stop condition for the solver is never met because beta would not be increasing.

* Adding dnn based super resolution module.

* Fixed whitespace error in unit test

* Fixed errors with time measuring functions.

* Updated unit tests in dnn superres

* Deleted unnecessary indents in dnn superres

* Refactored includes in dnn superres

* Moved video upsampling functions to sample code in dnn superres.

* Replaced couts with CV_Error in dnn superres

* Moved benchmarking functionality to sample codes in dnn superres.

* Added performance test to dnn superres

* Resolve buildbot errors

* update dnn_superres

- avoid highgui dependency
- cleanup public API
- use InputArray/OutputArray
- test: avoid legacy test API

* Add pattern generator tool

* Fix help error

* Update readme

* Fix bug: Invalid Syntax at line 14(draw_motion_comp method)

* Fix bug: TypeError- integer argument expected, got float

* Fix bug: clean up the camera by adding .release()

* removed private flann documentation
* common tutorial images moved to doc/images
* grouping issues
