Modification on Brightness Enhancement for Simple Thresholding in Eyelid Area Measurement

Abstract: This study aims to calculate eyelid area to classify eye condition become awake or drowsy as the initial stage of a drowsiness detection system. This work used 40x95 matrix of 500 single eye images from 4 respondents. The input image will be processed into brightness enhancement, grayscaling, thresholding and eyelid area measurement. The problem of thresholding process was to determine the optimal threshold value that can be used on images with different intensities. Brightness enhancement modification is prop… Show more

“…Figure 6 shows the bounding box section to be enlarged. Equation (4)-(7) can be used to increase the size of a bounding box (Indrabayu and Areni, 2017 Where: a = The distance from the leftmost border of the frame to the bounding box's left margin b = The distance from the topmost border of the frame to the top margin of the bounding box c = The length of the bounding box d = The width of the bounding box Figure 7 shows the example of the output frame obtained from the cropping process.…”
