Resize images to size using the specified interpolation method.

Usage

op_image_resize(
  image,
  size,
  interpolation = "bilinear",
  antialias = FALSE,
  data_format = "channels_last"
)

Arguments

image

Input image or batch of images. Must be 3D or 4D.

size

Size of output image in (height, width) format.

interpolation

Interpolation method. Available methods are "nearest", "bilinear", and "bicubic". Defaults to "bilinear".

antialias

Whether to use an antialiasing filter when downsampling an image. Defaults to FALSE.

data_format

string, either "channels_last" or "channels_first". The ordering of the dimensions in the inputs. "channels_last" corresponds to inputs with shape (batch, height, width, channels) while "channels_first" corresponds to inputs with shape (batch, channels, height, weight). It defaults to the image_data_format value found in your Keras config file at ~/.keras/keras.json. If you never set it, then it will be "channels_last".

Value

Resized image or batch of images.

Examples

x <- random_uniform(c(2, 4, 4, 3)) # batch of 2 RGB images
y <- op_image_resize(x, c(2, 2))
shape(y)

## shape(2, 2, 2, 3)

x <- random_uniform(c(4, 4, 3)) # single RGB image
y <- op_image_resize(x, c(2, 2))
shape(y)

## shape(2, 2, 3)

x <- random_uniform(c(2, 3, 4, 4)) # batch of 2 RGB images
y <- op_image_resize(x, c(2, 2), data_format = "channels_first")
shape(y)

## shape(2, 3, 2, 2)
