Convolutional Neural Network to classify two classes images

I have sets images of two classes saved in two different folders. The task is to use these image datasets to train and validate the CNN algorithm. The code for this already being written and can be accessed via the following link
https://www.tensorflow.org/tutorials/images/cnn

Your task basically is to use my image datasets which are of two classes and implement them using linked code and then improve accuracy.

Since code is already written, I hope it would not take more time and effort.
