- renamed IntensityNormNormalizationFilter to UnityNormFilter
- added GammaCorrectionFilter and GreyWorldNormalizationFilter
- sped up the histogram feature extractors a bit
- added the possibility to SpatialHistogramFeatureExtractor to add a pixel to the four surrounding cell histograms by interpolation bilinearly
- added type-check to histogram extractors
- added comment to class documentation explaining the expected patch data
Merge branch 'refact' of github.com:elador/FeatureDetection into refact
- fixed CMake configuration problems by commenting out the render libs and apps
- fixed problematic exception messages
- fixed the type/depth check within the histogram feature extractors
- made SpatialHistogramFeatureExtractor a bit more speedy
- added ExtendedHogExtractor for better and smaller HOG-like features
fixed the channels condition of SpatialHistogramFeatureExtractor
- renamed the histogram filters to binning filters as their purpose is better described by the new name (they do not create histograms but images containing bin information per pixel)
- removed unnecessary block size from ExtendedHogExtractor
converted the histogram and hog feature extractors to image filters
- added many new image filters
- renamed MultipleImageFilter to ChainedFilter
- added a default implementation of applyInPlace to ImageFilter
- added a feature extractor that increases the size of the patch by one to be able to correctly work with integral images
Merge branch 'refact' of github.com:elador/FeatureDetection into refact
- fixed Vertex.hpp
- prevented libRender, generateSyntheticLandmarkDataKlaus and 3dmmRendererGUI from being built (do not work in linux right now)
