Submitting SegDataGenerator to Keras?

[ahundt]

Would you be interested in submitting or giving permission to submit SegDataGenerator to keras?

It would first go through keras-contrib as per the Keras instructions for pull requests.

I wouldn't mind doing the integration, I can make sure credit is properly given as well.

Of course it'll be great if you can help submitting it. But you need to make sure it can support 'th' dim_ordering correctly, which I've never checked. And I guess it's also needed to fix lots of my dirty codes...... Anyway it will be really appreciated if you can help, at least this can give an example for those who wanna use keras to do image segmentation.

Just to update, I've been doing some code cleanup and working to get all the pieces in so an example can also be included in keras-contrib. I've submitted pull requests for:

• mscoco coco.py mscoco dataset support keras-team/keras-contrib#81, and pascal voc -
  pascal_voc.py pascal voc 2012 dataset support keras-team/keras-contrib#80. Here is the issue for the datasets additional datasets - coco + voc2012 keras-team/keras-contrib#47.

Eventually, the code, particularly SegDataGenerator, will likely need to be moved to most likely an image.py in keras_contrib/preprocessing equivalent to the location of ImageDataGenerator in keras.

The model creation code might then go into applications, and train.py would go into a single file with multiple command line options in https://github.com/farizrahman4u/keras-contrib/tree/master/examples.

It may be possible to handle the tensorflow vs theano part later on, as long as tf isn't called directly in anything under keras_contrib that is not in the tensorflow backend.

Update: François Chollet, Keras' author, said he is interested in directly incorporating dense prediction/FCN into the Keras API, so I'm seeking suggestions/feedback at keras-team/keras#6538

@ahundt @aurora95 I tried to add SegDataGenerator to my utils in my source. I cannot import it from there after rebuilding keras python setup.py install.
I'm not sure if its a general question or particular to this code.

[ahundt]

@Irtza I'd appreciate if your question could be in a separate github issue. A setup.py pull request would be welcome, or just add it to your PYTHONPATH.

Okay I will add more details on the roadblocks while using the segDataGenerator in another issue on this repo
