Abstract

Disclosed is a line-of-sight detection method, including a step SA1 and a step SA2. The step SA1 performs a dynamic-threshold-to-switch action to correct the error of the data generated in the previous facial feature detection step. Furthermore, the step SA2 performs an eye-ROI-filtering action serving as a pretreatment step to filter a plurality of eye-ROI images and establish a sample set.
