Enhance the cropping technique for data augmentation

[yashk2000]

The cropping technique for data augmentation is a bit menial.
It just scales in the image from one view.
I have included a technique to scale in the image from multiple views and hance providing around 4-5 samples with different views of each image. This will increase the size of the dataset of each object and hence help improve the accuracy of the model when it is trained.
