示例1: __init__
# 需要導入模塊: from menpo.transform import Homogeneous [as 別名]
# 或者: from menpo.transform.Homogeneous import compose_before [as 別名]
def __init__(self, image_shape):
# flip axis 0 and axis 1 so indexing is as expected
flip_xy = Homogeneous(np.array([[0, 1, 0],
[1, 0, 0],
[0, 0, 1]]))
# scale to get the units correct
scale = Scale(image_shape)
self.flip_and_scale = flip_xy.compose_before(scale)示例2: test_homog_compose_before_nonuniformscale
# 需要導入模塊: from menpo.transform import Homogeneous [as 別名]
# 或者: from menpo.transform.Homogeneous import compose_before [as 別名]
def test_homog_compose_before_nonuniformscale():
homog = Homogeneous(np.array([[0, 1, 0],
[1, 0, 0],
[0, 0, 1]]))
s = NonUniformScale([3, 4])
res = homog.compose_before(s)
assert(type(res) == Homogeneous)
assert_allclose(res.h_matrix, np.array([[0, 3, 0],
