-### Test These Scenarios:
-1. **Multiple Sessions**: Start and stop inference 3-5 times → Should not crash
-2. **Long Running**: Let it run for 1 hour → Performance should stay consistent  
-3. **FPS Check**: Watch FPS numbers → Should be steady around 4-5 FPS, not jumping wildly
-4. **Memory Check**: Monitor system memory → Should not keep growing over time

-### Expected Results:
-- No application crashes
-- Stable FPS readings  
-- Memory usage stays controlled
-- System responds quickly to new camera frames
