tfm.vision.preprocess_ops.normalize_scaled_float_image

Normalizes a scaled float image to zero mean and unit variance.

It assumes the input image is float dtype with values in [0, 1).

image A tf.Tensor in float32 dtype with values in range [0, 1).
offset A tuple of mean values to be subtracted from the image.
scale A tuple of normalization factors.

A normalized image tensor.
