“…In this particular case, the channels c with an A c , estimated by Equation (8), of 12 were classified as the full-time case, while the channels c with an A c between 1 and 11 were classified as the part-time case. In a full-time case, the black pixels represented on Channel 6,11,34,35,37,43,44,68,69, and 81 overall sampling times. In a part-time case, the alternating of black and white pixels represented on Channel 4, 9, 18, 31, 60, 61, 63, 66, and 79 overall sampling times.…”
