Example #1

File: test_functional.py Project: zhouhan921001/albumentations

def test_random_contrast_float(alpha, expected):
    img = np.ones((100, 100, 3), dtype=np.float32) * 0.4
    expected = np.ones((100, 100, 3), dtype=np.float32) * expected
    img = F.random_contrast(img, alpha)
    assert img.dtype == np.dtype('float32')
    assert_array_almost_equal_nulp(img, expected)

Example #2

def test_random_contrast(alpha, expected):
    img = np.ones((100, 100, 3), dtype=np.uint8) * 127
    img = F.random_contrast(img, alpha)
    assert img.dtype == np.dtype('uint8')
    assert (img == expected).all()
