Merged Cresson Remi requested to merge dataset into develop

Introducing OTBTF python classes.

  • PatchesReaderBase: base abstract class for patches readers. Users/developers can implement their own from it.
  • PatchesImagesReader: a class implementing PatchesReaderBase to access the patches images, as they are produced by the PatchesExtraction application.
  • IteratorBase: base class to iterate on PatchesReaderBase-derived readers.
  • RandomIterator: an iterator implementing IteratorBase designed to randomly access elements.
  • Dataset: generic class to build datasets, consisting essentially of the assembly of a PatchesReaderBase-derived reader, and a IteratorBase-derived iterator. The Dataset handles the gathering of the data using a thread. It can be used as a tf.dataset to feed computational graphs.
