How to output only the uv map without original picture in densepose?

Question

I'm using Densepose in detectron2 .The type of output I get is as shown in the image below [enter image description here][1]

But I want to get the output with black background like this [enter image description here][2]

Is there a way to help me do this? Thanks. [1]: https://i.stack.imgur.com/Lo2uZ.jpg [2]: https://i.stack.imgur.com/BQ8Zh.png
