Adjust the saturation of one or more images.

images is a tensor of at least 3 dimensions. The last dimension is interpreted as channels, and must be three.

The input image is considered in the RGB colorspace. Conceptually, the RGB colors are first mapped into HSV. A scale is then applied all the saturation values, and then remapped back to RGB colorspace.

images A Tensor. Must be one of the following types: half, float32. Images to adjust. At least 3-D.
scale A Tensor of type float32. A float scale to add to the saturation.
name A name for the operation (optional).

A Tensor. Has the same type as images.
