/**
* \class TensorflowMultisourceModelBase
* \brief This filter is base for TensorFlow model over multiple input images.
* \brief This filter is the base class for all TensorFlow model filters.
*
* The filter takes N input images and feed the TensorFlow model.
* Names of input placeholders must be specified using the
* SetInputPlaceholdersNames method
* This abstract class implements a number of generic methods that are used in
* filters that use the TensorFlow engine.
*
* The filter has N input images (Input), each one corresponding to a placeholder
* that will fed the TensorFlow model. For each input, the name of the
* placeholder (InputPlaceholders, a std::vector of std::string) and the
* receptive field (InputReceptiveFields, a std::vector of SizeType) i.e. the
* input space that the model will "see", must be provided. Hence the number of
* input images, and the size of InputPlaceholders and InputReceptiveFields must
* be the same. If not, an exception will be thrown during the method
* GenerateOutputInformation().
*
* The TensorFlow graph and session must be set using the SetGraph() and
* SetSession() methods.
*
* Target nodes names of the TensorFlow graph that must be triggered can be set
* with the SetTargetNodesNames.
*
* The OutputTensorNames consists in a strd::vector of std::string, and
* corresponds to the names of tensors that will be computed during the session.
* As for input placeholders, output tensors field of expression
* (OutputExpressionFields, a std::vector of SizeType), i.e. the output
* space that the TensorFlow model will "generate", must be provided.
*
* Finally, a list of scalar placeholders can be fed in the form of std::vector
* of std::string, each one expressing the assigment of a signle valued
* placeholder, e.g. "drop_rate=0.5 learning_rate=0.002 toto=true".
* See otb::tf::ExpressionToTensor() to know more about syntax.
