- HistogramIntersectionKernel, RbfKernel, libSvm and libLinar can now cope with multi-channel images/vectors
- changed HogFilter and ExtendedHogFilter to create a multi-channel image that contains the block/cell descriptors in each "pixel"
- added CompleteExtendedHogFilter that starts with the gradient compution (like a combination of GradientFilter, GradientBinningFilter and ExtendedHogFilter)
- added CellBasedPyramidFeatureExtractor that computes an ImagePyramid that consists of cells (e.g. HOG-Cells)
- added ImagePyramid::getLayerScales() and PyramidFeatureExtractor::getLayerScales() to retrieve the indices and scale factors of the image pyramid layers (used by CachingPyramidFeatureExtractor)
Merge branch 'master' of github.com:elador/FeatureDetection
Experiments with the ogl depth-buffer
New try at a software-renderer. Test-app
Merge remote-tracking branch 'origin/master' into swrend
Updated MatrixUtils::create*Matrix to return the same matrices as OpenGL/Qt, plus added a createOrtho

Finished outline of the new software-renderer
Moved new software renderer stuff to a separate class
Finally fixed the software-renderer bug where it would draw black spots with small triangles
Merge remote-tracking branch 'origin/master' into swrend
- Added working backface-culling and a boolean to enable it

- added view-frustum culling (not tested yet)
Proper file-renaming (capital case) of LogLevels.hpp
Renamed logLevelToString-function (capital L), removed using-directive from LogLevels
Merge remote-tracking branch 'origin/master' into swrend
changes in conjunction with ECCV 2014 publication
- changed image pyramid to use octave-based creation
- added new landmark source for simple CSV files
- added app for playing videos, showing rectangular landmarks and saving videos
- added new measurement model that is based on extended HOG features
- added new extended HOG feature extractor that combines everything from gradient computation to descriptor building
- added some more stuff
- fixed few bugs
