    \brief The FeatureLearning allows connecting to ArmarX ImageProviders and extract features from their images.
 
    \image html FeatureLearning.png
    The user can connect and disconnect ImageProviders easily. By clicking on the image, a region can be chosen. SIFT features are calculated within the region. After features have been added to the selection, they can be saved to a file. Additionally, the features can be saved to an object in the PriorMemory, if it is available. Loading from the memory or a file is also supported.
