Video frame rate influences the accuracy of blink dynamics measurement

Video frame rate significantly impacts the accuracy of certain blink metrics. Low frame rates may be sufficient for estimating blink amplitude and duration, while velocity metrics require higher sampling. A minimum of 250 fps is recommended for a comprehensive assessment of blink dynamics.

Abstract

Video frame rate significantly impacts the accuracy of certain blink metrics. Low frame rates may be sufficient for estimating blink amplitude and duration, while velocity metrics require higher sampling. A minimum of 250 fps is recommended for a comprehensive assessment of blink dynamics.
