Adversarial example using FGSM Neural style transfer TensorFlow Addons Image: Operations Image Super Resolution using ESRGAN Artistic Style Transfer with TensorFlow Lite

Detects whether an image is a BMP, GIF, JPEG, or PNG, and performs the appropriate operation to convert the input bytes string into a Tensor of type dtype.

Args
`contents`	0-D `string`. The encoded image bytes.
`channels`	An optional `int`. Defaults to `0`. Number of color channels for the decoded image.
`dtype`	The desired DType of the returned `Tensor`.
`name`	A name for the operation (optional)
`expand_animations`	Controls the shape of the returned op's output. If `True`, the returned op will produce a 3-D tensor for PNG, JPEG, and BMP files; and a 4-D tensor for all GIFs, whether animated or not. If, `False`, the returned op will produce a 3-D tensor for all file types and will truncate animated GIFs to the first frame.

Returns
`Tensor` with type `dtype` and a 3- or 4-dimensional shape, depending on the file type and the value of the `expand_animations` parameter.

Raises
`ValueError`	On incorrect number of channels.
