Looking good so far. I think you might want to show the xray picture before the median filter so that folks have a before and after.

Could you click the "x" on the top left of this output to remove the install logging.

Also please use

!pip install tensorflow-gpu==2.0.0-beta1

!pip install tensorflow-addons

TFA should be 0.4

Please update this to say something like "Here is the list of image operations we'll be covering in this example"

We try to stay away from using anything tensorflow.python as these are private API calls. Could You use PIL instead since it's already imported?

Likewise remove the logging info

This warning should go away if using tf2-beta

[seanpmorgan]

Is this the expected output we want to show?

Looking good @parth-p! Few changes requested

[seanpmorgan]

One more thing... could you move the file to examples/image_ops.ipynb

[WindQAQ]

I'd support we could use tf.io.read_file directly so that we do not need to access the private API.

Suggestions for this:

1. Larger values of flows are better to observe the changes.
2. I think flows are not necessary to be a tf.Variable. Using tf.convert_to_tensor or even passing numpy array directly is enough in our implementation.

Thank you @parth-p! I leave some comments above. Don't forget to remove unused import statement (import cv2). Please check it out. Moreover, we might want to unify our examples' style. Please follow the template.
