Abstract
ÐSophisticated mathematical algorithms (such as differencing, thresholding, aggregation and statistical analysis of skin colours) are used to compare successive frames of computer-captured images of the face. From these, changes in state of the eyes are determined and are used to detect blinks. A recognition performance of 83.74+0.03% is achieved over ®ve subjects with a low rate of false positives 2.71+0.01%. A logical decision rule identi®es purposeful blinks and applies them to control either a custom-designed communication package or an external device.
