[3rd attempt] fixed HOGDescriptor::detectMultiScale() to group weights as well as ROIs
Reverted back to the previous method where a public method groupRectangles was added to HOGDescriptor to take care of ROI and weight grouping
Added spacing in a nested template argument list.
added documentation for OpenGL interoperability
Add super resolution's OpenCL implementation.
Accuracy and performance tests are also provided.
Fix build error.
PvAPI support on Windows with MinGW (PR #1038 applied to the branch 2.4)
add kmeans
Bugfix for an overlapping size of image and template for matchTemplate.

Example: img of size 10x10 and templ of size 11x9.
In subsequent code this will results in either width or height of
corrSize to be zero (0).
Line 261 will call crossCorr which will then have a zero size of either
blocksize.width or blocksize.height resulting in a division by zero
crach in lines 137 or 138.
remove the redundant function
Fixed issue 3130 (http://code.opencv.org/issues/3130), where one argument of the BRISK-call was ignored. Previously it was not possible to use BRISK without creating descriptors.
Now it behaves like ORB (and how it is documented), and you can call BRISK to just generate feature points and no descriptors.
fix the function name
Improve FPS on black and white Ximea cameras
Fix ocl gftt file name typo.
Add IPP support to integral function
xls-report.py: add ability to specify arbitrary sheet properties
xls-report.py: removed image size and type from the list of other parameters.

Also, shrunk the corresponding column and the test name column.
Added to the test log parser a crude ability to detect non-implemented tests.
Made the crude ability less crude.
xls-report.py: Added an option to show per-pixel times
