**• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description)**

I’m working with Deepstream 5.1 Python bindings. Have configured successfully output tensor metadata for custom post-processing of different models, and displayed with NVOsd. That works fine with rectangles, circles, text.

Now, I want to draw segmentation masks. I can’t find how to do this with Python.  
The only example available uses OpenCV and output image files.  
Is there any undocumented binding? Support in next releases?

Thanks!
