Rotate image(s) counter-clockwise by 90 degrees.

tf.image.rot90(
    image, k=1, name=None
)

Used in the notebooks

Used in the tutorials

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]] 

Args:

  • image: 4-D Tensor of shape [batch, height, width, channels] or 3-D Tensor of shape [height, width, channels].
  • k: A scalar integer. The number of times the image is rotated by 90 degrees.
  • name: A name for this operation (optional).

Returns:

A rotated tensor of the same type and shape as image.

Raises:

  • ValueError: if the shape of image not supported.
