Rotate image(s) by 90 degrees.
tf.image.rot90(
image, k=1, name=None
)
Used in the notebooks
For example:
a=tf.constant([[[1],[2]],
[[3],[4]]])
# rotating `a` counter clockwise by 90 degrees
a_rot=tf.image.rot90(a)
print(a_rot[...,0].numpy())
[[2 4]
[1 3]]
# rotating `a` counter clockwise by 270 degrees
a_rot=tf.image.rot90(a, k=3)
print(a_rot[...,0].numpy())
[[3 1]
[4 2]]
# rotating `a` clockwise by 180 degrees
a_rot=tf.image.rot90(a, k=-2)
print(a_rot[...,0].numpy())
[[4 3]
[2 1]]

name
|
A name for this operation (optional).
|
Returns |
