the respective srs as shown the penumbras 103 for the srs are set as rectangles the intensity levels 104 corresponding to the yawn in the raw video 105 impinge as in the eye case both on the umbral regions 102 and on the penumbral regions 103 in each of the srs the lateral inhibition process operates here exactly as for the eye case the hairline case again presents a somewhat different problem as shown in fig6 here the shape does not change so much as its location within the umbra penumbra complex therefore the umbra is trapezoidal 110 the penumbra is a modified rectangular shape 111 thus as a primarily vertically oriented cord of hair intensity within the hairline roi 112 corresponding to the hairline in the raw video 113 crosses an associated sr 114 moving centrally the ratio of umbral coverage to penumbral coverage increases resulting in an increasing civ for the sr sr 1 and sr 3 will show correlated increases in civ for movement centrally of the right hairline while the sr 2 and sr 4 will show correlated increases in civ for movement centrally of the left hairline the coordinates of the rois the vlfm intensity ranges for each of the srs and the shape equations governing the generation of the sdm umbras and penumbras are all preferably controlled by program parameters based on an initialization training session and all are.
