How to visualize the attention mask Mt?

[chenby008]

Hello, thank you for your excellent work.

I noticed that the attention mask Mt was visualized in this paper, and the pose attention transfer process is clear and explicable (Figure 5 in paper).

I tried a lot of tools myself, but I couldn't achieve the effect in the picture. Can you recommend the tools you used?

In addition, whether the attention mask needs to be optimized before visualization?

Thank you so much!
