Public Member Functions | |
MinMaxAverager () | |
void | add_image (EMData *image) |
To add an image to the Averager. | |

Get Averager parameter information in a dictionary. Each parameter has one record in the dictionary. Each record contains its name, data-type, and description.

Multiply the result image by some floating point constant This is useful when weighting the input images prior to calling add_image - a situation where it is likely you want to divide by the sum of the weights. Hence call mult after all of the weighted images have been added.
