first rescales so that the range of input values to is mapped to to .

ImageAdjust[image,corr,{inmin,inmax},{outmin,outmax}]
rescales so that the range of input values to is mapped to to .

DetailsDetails

  • 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.
