ImageAdjust

ImageAdjust [image]
adjusts the levels in image, rescaling them to cover the range to .
ImageAdjust
adjusts the contrast of image by an amount c.
ImageAdjust
adjusts the contrast by an amount c and the brightness by an amount b.
ImageAdjust
also performs a gamma correction by raising values to the power .
ImageAdjust
first rescales so that the range of input values to is mapped to to .
ImageAdjust
rescales so that the range of input values to is mapped to to .
  • ImageAdjust works with images involving any number of channels.
  • Zero adjustment corresponds to contrast adjustment , brightness adjustment , and gamma correction .
  • When rescaled values lie outside the range to , they are clipped.
  • All correction and range parameters can be given as lists to specify different treatment for different channels in the image.
  • Range parameters can be set to Automatic to indicate the minimum or maximum of the values that occur in the image.
  • When applied to color images, ImageAdjust always returns an RGB image.
