An efficient eye tracking procedure is presented providing a non-invasive method for real time detection of a subject pupils in a sequence of frames captured by low cost equipment. The procedure can be easily adapted to any application relying on eye tracking. The eye pupil identification is performed by a hierarchical optimal segmentation procedure: a contextual picture zoning yielding the eyes position, and a further binarization extracting the pupils coordinates. No eye movement model is required to predict the future eyes position to restrict the image searching area, since the procedure first step is fast enough to obtain a frame to frame eyes position update.

Abstract
An efficient eye tracking procedure is presented providing a non-invasive method for real time detection of a subject pupils in a sequence of frames captured by low cost equipment. The procedure can be easily adapted to any application relying on eye tracking. The eye pupil identification is performed by a hierarchical optimal segmentation procedure: a contextual picture zoning yielding the eyes position, and a further binarization extracting the pupils coordinates. No eye movement model is required to predict the future eyes position to restrict the image searching area, since the procedure first step is fast enough to obtain a frame to frame eyes position update.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
