[request]Figure 5 of DCGAN paper implementation

Hi,
I'm interested in the contents which is in section 6.2 VISUALIZING THE DISCRIMINATOR FEATURES of DCGAN paper.
I'm not sure I could understanding this part but, I failed to implement it.
I refered to #13 of the following page
https://github.com/Hvass-Labs/TensorFlow-Tutorials

please give me some tip or implementation code (doesn't matter at any code)
thanks in advance
