tf.image.central_crop(
image,
central_fraction
)
Defined in tensorflow/python/ops/image_ops_impl.py
.
Crop the central region of the image(s).
Remove the outer parts of an image but retain the central region of the image along each dimension. If we specify central_fraction = 0.5, this function returns the region marked with "X" in the below diagram.
--------
| |
| XXXX |
| XXXX |
| | where "X" is the central 50% of the image.
--------
This function works on either a single image (image
is a 3-D Tensor), or a
batch of images (image
is a 4-D Tensor).
Args:
image
: Either a 3-D float Tensor of shape [height, width, depth], or a 4-D Tensor of shape [batch_size, height, width, depth].central_fraction
: float (0, 1], fraction of size to crop
Raises:
ValueError
: if central_crop_fraction is not within (0, 1].
Returns:
3-D / 4-D float Tensor, as per the input.
