Hi Guys,

I’m using deepstream-nvdsanalytics example with Python and one question came up, there is any way to use an ROI with a cumulative count like LOI?

For example: Sum all people that passed in that region, because sometimes a line can’t fit into some places and instead of a line I need a Polygon.

The last question, can I change the number of counts on the ROI’s side?


Hey customer,
I think it’s similar as Can I get the accumulate number of objects passed ROI?

I did read the post, in the meantime, nothing new was added to DeepStream?

Because seems like it’s not the efficient way to do that. I’m gonna have about 30 IP cams and for each one, I need one 2 NumPy arrays, one with all IDS and another one with IDS that crossed the ROI.

We will consider to add the feature in later release.

I will keep following for updates, thanks @bcao.

Meanwhile, I will use that temporary solution.
