# count white pixels per box
def boxCount(img, bw, bh):
    # declare output list
    counts = [];
    h, w = img.shape[:2];
    for y in range(0, h - bh + 1, bh):
        line = [];
        for x in range(0, w - bw + 1, bw):
            # slice out box
            box = img[y:y+bh, x:x+bw];

            # count
            count = np.sum(box == 255);
            line.append(count);
        counts.append(line);
    return counts;
