transform_color_jitter {torchvision}

Randomly change the brightness, contrast and saturation of an image

Description

Randomly change the brightness, contrast and saturation of an image

Usage

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.
