I find a amazing tools for Data Augmentation It`s called Augmentor (http://augmentor.readthedocs.io/en/master/index.html)
Augmentor is a Python package designed to aid the augmentation and artificial generation of image data for machine learning tasks. It is primarily a data augmentation tool, but will also incorporate basic image pre-processing functionality.
you can combine the images and the Segmentation labels with preprocess_CV2.py if necessary. and you can use the preprocess_Augmentor.py to generate any num of images you want with input of the origin images path and output path
using $ pip install Augmentor
