Data augmentation: ImageDataGenerator vs openCV
$begingroup$
I want to increase the data in my dataset to create a CNN deep learning classification model.
Which is better for the model using data augmentation by ImageDataGenerator or using openCV to increase the data??
-- I am using Keras and floydhub..

Since you are using Keras, why not start withe Keras ImageDataGenerator?

Here is tutorial on how to make your own custom generator using opencv. Which you can expand as much as you want with your ideas.

Keras' ImageDataGenerator doesn't offer much support by itself for data augmentation. However it has a parameter called preprocessing_function which allows you to use custom augmentors with it.
I personally use imgaug which offers virtually any augmentation you can think of and works well with ImageDataGenerator like I said.

@N.IT you use theImageDataGeneratorto load the images just like you currently do it. imgaug just lets you make augmentation on-the-fly.
