class | CCDCore
class | CChebSeries
class | ColourGMMGPU
class | ColourHist2D
class | ContourCCD
class | DataFusion
| Static data fusion class. It inherits from the modalities:Modality interface, so it can be flexibly combined with the features. ASSUMPTIONS: the children output levels of one DataFusion class instance must be of the same level E.g. if you want to fuse the output of two pixel level children and one feature level child you have to cascade two DataFusion classes. DF1 instance fuses pixel level to feature level and DF2 instance fuses the output of DF1 with the feature level child. More...
class | DummyModality
class | HarrisKeypoints
class | HistoOrientedGrad
| Visual modality: Histogram of Oriented Gradients (HOG) This class implements the HOG on a reference pattern, to be matched to the current image It uses the integral HOG in order to speed up computations for multiple evaluations (e.g. particle filters) on a rectangular bounding box at a given pose.
