Detailed Description

simple algorithm to find pixels of interest

the algorithm is taken from Per Johnsons code and is just put into a functor.

User definable Parameters:: PixelDetectors/%name%/SimpleFinder/{Threshold}
The threshold above which the pixels have to be. Default is 0.

find the pixels

take the input frame and search it for pixels which are put into the list of pixels.
Go through the whole frame and check wether a pixel is above the threshold. If so then check whether the sourrounding pixels all have a smaller value. If this is the case and the pixel is not at the edge of the frame add the pixel to the list of pixels
