+**What it does**
+
+<![CDATA[
+
+Enhances image contrast by using either normalization (contrast stretching) or histogram
+equalization.
+
+Normalization (i.e., contrast stretching) attempts to improve the contrast in an image by
+stretching the range of intensity values it contains to span a desired range of values
+(e.g. the the full range of pixel values that the image type allows).  It differs from the
+more sophisticated histogram equalization in that it can only apply a linear scaling function
+to the image pixel values.  As a result the enhancement is less harsh.
+
+Histogram equalization provides a sophisticated method for modifying the dynamic range and
+contrast of an image by altering the image such that its intensity histogram has a desired
+shape.  Unlike contrast stretching, histogram modeling operators may employ non-linear and
+non-monotonic transfer functions to map between pixel intensity values in the input and output
+images.  Histogram equalization re-assigns the intensity values of pixels in the input image
+such that the output image contains a uniform distribution of intensities (i.e. a flat histogram).
+
+- **Equalize histogram** - Enhances the image using histogram equalization.  Choosing this option eliminates the "Saturated pixels pct" and "Normalize" options.
+- **Saturated pixels pct** - Determines the number of pixels in the image that are allowed to become saturated.  Increasing this value increases contrast.  This value should be greater than zero to prevent a few outlying pixels from causing the histogram stretch to not work as intended.
+- **Normalize** - Recalculates the pixel values of the image so the range is equal to the maximum range for the data type, or 0-1.0 for float images. The maximum range is 0-255 for 8-bit images and 0-65535 for 16-bit images.  Normalization of RGB images is not supported, so selecting "yes" is ignored for this image type.
