tf.raw_ops.RGBToHSV

Converts one or more images from RGB to HSV.

tf.raw_ops.RGBToHSV(
    images, name=None
)

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)
