transform_adjust_gamma: Adjust the gamma of an RGB image

Description Usage Arguments Details See Also

Description

Also known as Power Law Transform. Intensities in RGB mode are adjusted based on the following equation:

I_{\mbox{out}} = 255 \times \mbox{gain} \times ≤ft (\frac{I_{\mbox{in}}}{255}\right)^{γ}

Usage

1
transform_adjust_gamma(img, gamma, gain = 1)

Arguments

img

A magick-image, array or torch_tensor.

gamma

(float): Non negative real number, same as γ in the equation. gamma larger than 1 make the shadows darker, while gamma smaller than 1 make dark regions lighter.

gain

(float): The constant multiplier.

Details

See Gamma Correction for more details.
