Decodes PNG or JPEG raw bytes string into a RGB uint8 Tensor.

image_string A tf.Tensor of type strings with the raw PNG or JPEG bytes where the first dimension is timesteps.
channels Number of channels of the PNG image. Allowed values are 0, 1 and

  1. If 0, the number of channels will be calculated at runtime and no static shape is set.

A Tensor of shape [T, H, W, C] of type uint8 with the decoded images.
