tf.raw_ops.RGBToHSV

robots: noindex

Converts one or more images from RGB to HSV.

Outputs a tensor of the same shape as the images tensor, containing the HSV value of the pixels. The output is only well defined if the value in images are in [0,1].

output[..., 0] contains hue, output[..., 1] contains saturation, and output[..., 2] contains value. All HSV values are in [0,1]. A hue of 0 corresponds to pure red, hue 1/3 is pure green, and 2/3 is pure blue.

Usage Example:

blue_image = tf.stack([
   tf.zeros([5,5]),
   tf.zeros([5,5]),
   tf.ones([5,5])],
   axis=-1)
blue_hsv_image = tf.image.rgb_to_hsv(blue_image)
blue_hsv_image[0,0].numpy()
array([0.6666667, 1. , 1. ], dtype=float32)

images A Tensor. Must be one of the following types: half, bfloat16, float32, float64. 1-D or higher rank. RGB data to convert. Last dimension must be size 3.
name A name for the operation (optional).

A Tensor. Has the same type as images.
