Resize images
to size
using the specified method
.
tf.compat.v1.image.resize( images, size, method=ResizeMethodV1.BILINEAR, align_corners=False, preserve_aspect_ratio=False, name=None )
Resized images will be distorted if their original aspect ratio is not the same as size
. To avoid distortions see tf.image.resize_with_pad
or tf.image.resize_with_crop_or_pad
.
The method
can be one of:
tf.image.ResizeMethod.BILINEAR
: Bilinear interpolation.
tf.image.ResizeMethod.NEAREST_NEIGHBOR
: Nearest neighbor interpolation.
tf.image.ResizeMethod.BICUBIC
: Bicubic interpolation.
tf.image.ResizeMethod.AREA
: Area interpolation.The return value has the same type as images
if method
is tf.image.ResizeMethod.NEAREST_NEIGHBOR
. It will also have the same type as images
if the size of images
can be statically determined to be the same as size
, because images
is returned in this case. Otherwise, the return value has type float32
.
Args | |
---|---|
images | 4-D Tensor of shape [batch, height, width, channels] or 3-D Tensor of shape [height, width, channels] . |
size | A 1-D int32 Tensor of 2 elements: new_height, new_width . The new size for the images. |
method | ResizeMethod. Defaults to tf.image.ResizeMethod.BILINEAR . |
align_corners | bool. If True, the centers of the 4 corner pixels of the input and output tensors are aligned, preserving the values at the corner pixels. Defaults to False . |
preserve_aspect_ratio | Whether to preserve the aspect ratio. If this is set, then images will be resized to a size that fits in size while preserving the aspect ratio of the original image. Scales up the image if size is bigger than the current size of the image . Defaults to False. |
name | A name for this operation (optional). |
Raises | |
---|---|
ValueError | if the shape of images is incompatible with the shape arguments to this function |
ValueError | if size has invalid shape or type. |
ValueError | if an unsupported resize method is specified. |
Returns | |
---|---|
If images was 4-D, a 4-D float Tensor of shape [batch, new_height, new_width, channels] . If images was 3-D, a 3-D float Tensor of shape [new_height, new_width, channels] . |
