img_random_hsv_in_yiq: Random hsv in yiq

Description

Adjust hue, saturation, value of an RGB image randomly in YIQ color

Usage

img_random_hsv_in_yiq(
  image,
  max_delta_hue = 0,
  lower_saturation = 1,
  upper_saturation = 1,
  lower_value = 1,
  upper_value = 1,
  seed = NULL,
  name = NULL
)

Arguments

image

RGB image or images. Size of the last dimension must be 3.

max_delta_hue

float. Maximum value for the random delta_hue. Passing 0 disables adjusting hue.

lower_saturation

float. Lower bound for the random scale_saturation.

upper_saturation

float. Upper bound for the random scale_saturation.

lower_value

float. Lower bound for the random scale_value.

upper_value

float. Upper bound for the random scale_value.

seed

An operation-specific seed. It will be used in conjunction with the graph-level seed to determine the real seeds that will be used in this operation. Please see the documentation of set_random_seed for its interaction with the graph-level random seed.

name

A name for this operation (optional).

Value

3-D float tensor of shape `[height, width, channels]`.

Raises

ValueError: if `max_delta`, `lower_saturation`, `upper_saturation`, `lower_value`, or `upper_value` is invalid.

Details

space. Equivalent to `adjust_yiq_hsv()` but uses a `delta_h` randomly picked in the interval `[-max_delta_hue, max_delta_hue]`, a `scale_saturation` randomly picked in the interval `[lower_saturation, upper_saturation]`, and a `scale_value` randomly picked in the interval `[lower_saturation, upper_saturation]`.

Examples

# NOT RUN {
# }
# NOT RUN {
delta = 0.5
lower_saturation = 0.1
upper_saturation = 0.9
lower_value = 0.2
upper_value = 0.8
rand_hsvinyiq = img_random_hsv_in_yiq(img, delta,
lower_saturation, upper_saturation,
lower_value, upper_value)
)
# }
# NOT RUN {
