I want to draw an ROI area for each flow on the screen displayed by Nveglessink so that I can make a judgment. How should I do that in deepstream-test3?

What do you mean by so that I can make a judgment?

Whether the identified object is within the ROI region is determined by the naked eye

i use:

            rect = display_meta.rect_params[0]
            x, y , w, h = MyConfigReader.cfg_dict["ROI"][f"source{frame_meta.pad_index}"].split(",")
            rect.left = int(x) 
            rect.top = int(y) 
            rect.width = int(w) 
            rect.height = int(h) 
            rect.border_width = 3 
            rect.border_color.red = 0.0
            rect.border_color.green = 0.0
            rect.border_color.blue = 1.0
            rect.border_color.alpha = 1.0
            pyds.nvds_add_display_meta_to_frame(frame_meta, display_meta)

In the probe,Is that possible?
