An exposure recognition field algorithm is applied to the image data to1. distinguish the gray shade values inside the exposure field from those on the outside.2. ensure the histogram has the correct shape.3. identify the volume of interest before rescaling.4. identify the volume of interest after rescaling.5. reshape the histogram.
