The Physics of Light
Melanin absorbs light across multiple wavelengths. Darker skin reflects eighteen percent less light than lighter skin, creating immediate data disadvantage for camera sensors.
Distance Amplifies Differences
As distance increases, reflected light follows inverse square law. At twelve meters, darker skin returns thirty-five percent less usable data to sensors than lighter skin.
Sensor Limitations
Standard CMOS sensors cannot capture full dynamic range needed. Dark regions lose detail first, compounded by video compression algorithms used in systems.
The 30-Meter Problem
At typical security camera distances, physics creates forty-five percent accuracy gap. This represents fundamental interaction of light and matter in recognition systems.
