Randomly change the brightness, contrast and saturation of an image

transform_color_jitter(
  img,
  brightness = 0,
  contrast = 0,
  saturation = 0,
  hue = 0
)

Arguments

img	A `magick-image`, `array` or `torch_tensor`.
brightness	(float or tuple of float (min, max)): How much to jitter brightness. `brightness_factor` is chosen uniformly from `[max(0, 1 - brightness), 1 + brightness]` or the given `[min, max]`. Should be non negative numbers.
contrast	(float or tuple of float (min, max)): How much to jitter contrast. `contrast_factor` is chosen uniformly from `[max(0, 1 - contrast), 1 + contrast]` or the given `[min, max]`. Should be non negative numbers.
saturation	(float or tuple of float (min, max)): How much to jitter saturation. `saturation_factor` is chosen uniformly from `[max(0, 1 - saturation), 1 + saturation]` or the given `[min, max]`. Should be non negative numbers.
hue	(float or tuple of float (min, max)): How much to jitter hue. `hue_factor` is chosen uniformly from `[-hue, hue]` or the given `[min, max]`. Should have 0<= hue <= 0.5 or -0.5 <= min <= max <= 0.5.
