Adding More Augmentation.

[kartikdutt18]

Hey everyone,
Recently Augmentation class was added. It currently supports only resize function. This issue aims to add other augmentations as well.
Background :

1. Each augmentation must be accessible by passing string to the class.
2. Each Transform should have same function definition as ResizeTransform.
3. Idea is to create a map of function pointers and call respective function based upon the string type.

Some augmentations that would be really nice to see would be horizontal flip, vertical flip and gaussian noise. Thanks a lot.

are we going for something like keras ImageGenerator

tf.keras.preprocessing.image.ImageDataGenerator(
featurewise_center=False, samplewise_center=False,
featurewise_std_normalization=False, samplewise_std_normalization=False,
zca_whitening=False, zca_epsilon=1e-06, rotation_range=0, width_shift_range=0.0,
height_shift_range=0.0, brightness_range=None, shear_range=0.0, zoom_range=0.0,
channel_shift_range=0.0, fill_mode='nearest', cval=0.0, horizontal_flip=False,
vertical_flip=False, rescale=None, preprocessing_function=None,
data_format=None, validation_split=0.0, dtype=None
)

?
If yes, I wish to contribute but I'm totally new to mlpack and don't really understand it's functioning as of now, will you please guide me on what should I read upon to be able to contribute.
Thanks

Hey @rakeshbhugra, Right. We already have LoadFromDirectory functionality and augmentation class that currently only supports resize function. The issue aims to add more functions like horizontal-flip etc. Usage about the functions implemented can be found here. So you would have to open a PR adding some of the augmentations that you mentioned. Welcome to the community.
Regards.
