Detailed Description

will find pixels by comparing them to a "noise" map

This HLL like finding of pixels will compare the pixel values to a "noise" Map (see cass::pixeldetector::CommonData::noiseMap).

Note

the multiplication should be done here since if we do it on the global noise map it will be the same for all detectors

Todo:

is this right?

User definable Parameters:

PixelDetectors/%name%/AboveNoiseFinder/{Multiplier}
Value multiplied to the noise value before comparing whether the pixel is above the noise. Default is 4.

AboveNoiseFinder::pixels_t & AboveNoiseFinder::operator() ( const Frame &  frame, pixels_t &  pixels  )

virtual

find the pixels

take the input frame and search it for pixels which are put into the list of pixels.

Will go through the whole frame and compare each pixel whether its value is bigger than _multiplier * noise taken from the noiseMap. If this is the case it will be added to the list of pixels.

Returns

reference to the coalesced pixel list

Parameters

frame	the frame containing the pixels of interest
pixels	the list of pixels that should be found
