Test results

Performance testing

For performance testing, we took a video of a corridor with a flow of people moving at a speed of 5-10 people/sec. The volume of the database for identification is 249 persons.

Metrics

Metric name Description
Maximum Maximum value of parameters (CPU load, GPU load, amount of RAM, amount of VRAM) for the entire test time
95th percentile
  • CPU is loaded at no more than the specified value for 95% of the test time
  • GPU is loaded at no more than the specified value for 95% of the test time
  • The amount of RAM used does not exceed the specified value for 95% of the test time
  • The amount of VRAM used does not exceed the specified value for 95% of the test time
Median
  • CPU is loaded at no more than the specified value for 50% of the test time
  • GPU is loaded at no more than the specified value for 50% of the test time
  • The amount of RAM used does not exceed the specified value for 50% of the test time
  • The amount of VRAM used does not exceed the specified value for 50% of the test time
Recall Percentage of identified faces
Precision Percentage of correct identification
Max latency Max time spent between event generation and submission
Total events out of 117 This number shows how many identification events were generated during the test (Maximally the test result should contain 117 identification events)
