explanation of theload_image function and the dataflow

[wyli]

#31 and #34 asked for clarifications of load_image(filename):

how the image data is transferred to the network?
I can't find where the load_image(filename) function is called in the application_driver.py.

I know the niftynet defines the load_image(filename) function in niftynet/io/misc_io.py. However, I don't find how the load_image is called in promise 2012 demo.
there is no load_image function in both application_driver.py and segmentation_application.py.

Yes in the application you call the sampler and load the image using Sampler's "pop_batch_op", instead of feeding data in "sess.run(variables, feed_data_dict = data_dict)".

Although I haven't found how the image augmentation is implemented...

The load_image function is use in image_type.py ultimately in the implementation of ImageFactory. This is used eventually by ImageReader in image_reader.py which does the actual work of loading images and creating the image dictionary passed onto the network. In the application definitions ImageReader is instantiated for each set of input and stored in self.readers.
