tf.contrib.receptive_field.compute_receptive_field_from_graph_def

Computes receptive field (RF) parameters from a Graph or GraphDef object.

tf.contrib.receptive_field.compute_receptive_field_from_graph_def(
    graph_def, input_node, output_node, stop_propagation=None, input_resolution=None
)

The algorithm stops the calculation of the receptive field whenever it encounters an operation in the list stop_propagation. Stopping the calculation early can be useful to calculate the receptive field of a subgraph such as a single branch of the inception network.

Args
graph_def	Graph or GraphDef object.
input_node	Name of the input node or Tensor object from graph.
output_node	Name of the output node or Tensor object from graph.
stop_propagation	List of operations or scope names for which to stop the propagation of the receptive field.
input_resolution	2D list. If the input resolution to the model is fixed and known, this may be set. This is helpful for cases where the RF parameters vary depending on the input resolution (this happens since SAME padding in tensorflow depends on input resolution in general). If this is None, it is assumed that the input resolution is unknown, so some RF parameters may be unknown (depending on the model architecture).

Returns
rf_size_x	Receptive field size of network in the horizontal direction, with respect to specified input and output.
rf_size_y	Receptive field size of network in the vertical direction, with respect to specified input and output.
effective_stride_x	Effective stride of network in the horizontal direction, with respect to specified input and output.
effective_stride_y	Effective stride of network in the vertical direction, with respect to specified input and output.
effective_padding_x	Effective padding of network in the horizontal direction, with respect to specified input and output.
effective_padding_y	Effective padding of network in the vertical direction, with respect to specified input and output.

Raises
ValueError	If network is not aligned or if either input or output nodes cannot be found. For network criterion alignment, see photos/vision/features/delf/g3doc/rf_computation.md
