3D array representation of images — image_to_array • keras

3D array that represents an image with dimensions (height,width,channels) or (channels,height,width) depending on the data_format.

image_to_array(img, data_format = c("channels_last", "channels_first"))

image_array_resize(
  img,
  height,
  width,
  data_format = c("channels_last", "channels_first")
)

image_array_save(
  img,
  path,
  data_format = NULL,
  file_format = NULL,
  scale = TRUE
)

Arguments

img: Image
data_format: Image data format ("channels_last" or "channels_first")
height: Height to resize to
width: Width to resize to
path: Path to save image to
file_format: Optional file format override. If omitted, the format to use is determined from the filename extension. If a file object was used instead of a filename, this parameter should always be used.
scale: Whether to rescale image values to be within 0,255
