Abstract : The Gray-scale Linear Mapper (GLM) software module is a general purpose digital image processing function that permits the user to interactively change the linear intensity transformation of the input image. Most images contain a wide range of pixel values, whether they include clouds, ocean and/or land scenes. Thus, assigning the available gray shades to the entire dynamic range of the image stretches the contrast and brightness to a limit that typically does not adequately enable the viewer to see the full detail inherent in the full precision of the image.
