 ## Overview
 <br/>Image augmentation is a technique that is used to artificially expand the data-set. 
 <br/>This is helpful when we are given a data-set with very few data samples
+
+## Working:
+- Here, I have used Keras ImageDataGenerator to perform Image Augmentation
+- Image data generator has to many factors that can be changed to get different images from the provided image.
+- some of them are:
+  - rotation_range
+  - width_shift_range
+  - height_shift_range
+  - brightness_range
+  - shear_range
+  - zoom_range            
+  - fill_mode
+  - horizontal_flip
+  - cval
+  - rescale
+
