How to use the aotools.image_processing function in aotools

def test_encircled_energy_func():
    data = numpy.random.rand(32, 32)
    x, y = image_processing.encircled_energy(data, eeDiameter=False)
    print(y.min(), y.max())
    assert len(x) == len(y)
    assert numpy.max(y) <= 1
    assert numpy.min(y) >= 0

def test_image_contrast():
    image = numpy.random.random((20, 20))
    contrast = image_processing.image_contrast(image)
    assert type(contrast) == float

def test_brightestPxl_single():
    img = numpy.random.random((10, 10))
    com = image_processing.brightestPxl(img, 0.3)
    assert(com.shape[0] == 2)
