Python sum_rect Examples

Example #1

def test_sum_rect():
    f = np.arange(800 * 160).reshape((800, 160)) % 7
    fi = surf.integral(f.copy())

    np.random.seed(22)
    for i in range(100):
        y0 = np.random.randint(1, 780)
        y1 = np.random.randint(y0 + 1, 799)
        x0 = np.random.randint(1, 150)
        x1 = np.random.randint(x0 + 1, 159)
        assert _surf.sum_rect(fi, y0, x0, y1, x1) == f[y0:y1, x0:x1].sum()
