Thanks a lot Fred. I will check the options you have suggested. I want to calculate 99th percentile value of the image and the 1st percentile of the image using the pixels and use these percentiles to level the image using black, white, and gamma. I will use 99th percentile as black, 1st percentile as white and gamma =1.
Do you know about any alternative method which can do this ? Please let me know, Thanks, Shameer On Fri, May 20, 2011 at 2:12 PM, Fred Weinhaus <f...@alink.net> wrote: > Can you clarify what you mean by: > > "I would like to find the various (say 99th, 1st percentile) for images." > > Are you talking about percentile from a histogram or pixel with those > graylevel values from the image? > > If the latter, you an make masks by thresholding at those percentages > and use that to mask the image so that ony those percentiles are > showing and the rest are transparent, for example. > > > > >ImageMagicians: > > > >Is there any routine to get the entire pixel values for a given image > using > >ImageMagick ? > >I would like to find the various (say 99th, 1st percentile) for images. > > > >Please let me know, > >Thanks, > >Shameer > _______________________________________________ > Magick-users mailing list > Magick-users@imagemagick.org > http://studio.imagemagick.org/mailman/listinfo/magick-users > _______________________________________________ Magick-users mailing list Magick-users@imagemagick.org http://studio.imagemagick.org/mailman/listinfo/magick-users
