= Histogram Operations = OSSIM provides histogram-based color enhancement options to change the output of your data based on a histogram file. Here's an example of one such histogram operation. * '''Auto''' Automatically adjusts the histogram based on the min and max histogram values. * '''Match''' Automatically adjusts the histogram to match another image. * '''Linear''' Performs a linear contrast stretch using a standard deviation from the mean (e.g. 1, 2, or 3) or a user defined min/max value.
