Great article! I find it very insightful and shows the hidden power of DeepStream SDK.

A small question: After Figure 1 there is a paragraph that starts with " Here are the performance metrics when yolov4 is applied over the entire frame compared to over the tile.", How can we see this comparison?

Thanks.

I have question is it possible to update ROI at runtime using NvDsPreprocessing or any other way?
