3D array representation of images
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
)img |
