Hi fellow Kagglers,
\nAfter going through this amazing EDA notebook by @ihelon , it is quite apparent that there is some salt-pepper or random noise along with the molecular structure diagram in most of the images.
\nAnd as per the organizers the noise might vary in the test set also. So, I was thinking adding augmented noise to the train-set as well should be a good idea.

\n

But I do not know how to add noise to images during augmentation step. Any link or resources will be quite helpful.

\n

I am very new to CV so it might sound as a very naïve question, but I really need to know this.

\n

Thanks in advance 😊

@manabendrarout Hi!
\nLook at this library albumentations.ai. I think this library is very easy and useful.
\nThe example of using these augmentations you can also look at one of my kernels, for example LEGO Minifigures - TensorFlow Tutorial

I didn't know that albumentations can be used so smoothly with TF 2.x, thanks for share your work.
