Detailed Description

Creates maps from the last number of maps.

The algorithm that calculates the running average (offset) and standard deviation is taken from here (last checked 30.01.2012): http://www-uxsup.csx.cam.ac.uk/~fanf2/hermes/doc/antiforgery/stats.pdf

User definable Map Creator List:: "moving": The maps will be created from the last few frames.

User definable Parameters:

PixelDetectors/%name%/CorrectionMaps/ChangingCreator/{NbrTrainingFrames}
The number of frames that should be collected for calculating the initial maps. Default is 50.

PixelDetectors/%name%/CorrectionMaps/ChangingCreator/{DoTraining}
Before updating collect a set of "training" frames from which the initial maps are created. This is recommended if one does not have or has an outdated noise and offset map. Default is false.

PixelDetectors/%name%/CorrectionMaps/ChangingCreator/{NbrOfAverages}
The number of past frames that should be taken into account when calculating the noise and offset map. Default is 50.

PixelDetectors/%name%/CorrectionMaps/ChangingCreator/{Multiplier}
How much bigger does the pixel value have to be than the noise before The pixel is not taken into account when calculating the offset and noise of that pixel. Default is 4.

PixelDetectors/%name%/CorrectionMaps/ChangingCreator/{AutoSaveSize}
Tells to save the noise and offset map and recalculate the correction map after this many frames. Default is 1e6.
