- added small value to norms in UnitNormFilter to prevent division by zero
- UnitNormFilter may be applied inline if the input is of type CV_32F
- added filter for creating gradient images based on integral images
- added filter for creating upright SURF-like feature vector
removed old experimental code from IntegralGradientFilter (other choice of rectangular areas used to compute gradient)
- added prototype for filtering image-files in DirectoryImageSource
- improved structure and runtime efficiency of histogram filters and exteded HOG filter
- added new specialized HOG filters
- reversed the meaning of the combine-flag of the SpatialHistogramFilter and renamed it to concatenate
- added a special variant to the SpatialHistogramFilter when the blocksize is one
- there are remaining TODOs within some of the changed/added filters that will be removed later
- added another parameter to PyramidFeatureExtractor::extract to enable skipping of layers
- added checks for the step parameters and region of interest to pyramid feature extractors
added one-class SVM
Changed initializer-list to push_back to be vs2012 compliant

- just for testing: added statismo
Removed FR statistics code from old app, added to frDbExp app
Renamed old FR test app to something appropriate
Worked on ffpDetectApp and libDetection to make it work better with FD and FFD
- Updated the ffpDetectApp configs, separated in several files

- Deleted some old ERT/FFD files
- Moved the 3DMM class from libRender to libShapeModels

- Changed the RANSAC code and re-coded it with cvPOSIT (alpha-version)
- ffpDetectApp currently using the RANSAC-stuff and not usable
Merge branch 'eladevnew' into refact
