Provided is a computer implemented method and interface for mapping image
intensities on a computing device. The processing method includes
displaying an image on a display device having a range of intensities,
subdividing the range of intensities from the image on the display device
into a set of intensity zones, associating each intensity zone with one
or more segments of a graphical diagram to be displayed on a computer
device and moving a partition separating the one or more segments of the
graphical diagram displayed on the computer device to change the
intensity levels of the displayed image.
