  1. raw image,
  2. image in the window with amplitudes above the threshold_low
    • few peaks at the edges were discarded by the window limits,
    • image still contains many 1-photon pixels, which need to be eliminated,
  3. smeared image,
  4. raw image with found peaks (marked by the red circles)
  5. zoom of the previous plot.

Example for Module ImgAlgos::ImgPeakFilter

Code Block

[ImgAlgos.ImgPeakFilter] 
source         = DetInfo(:Opal1000)
key            = peaks
threshold_peak = 5

Example for Module ImgAlgos::ImgPeakFinder and ImgAlgos::ImgPeakFilter for CSPad

Module ImgAlgos::ImgPeakFinder works on image. In order to apply this algorithm to CSPad the image should be produced. In next example the image is produced using consequtive modules cspad_mod.CsPadCalib, ImgAlgos.CSPadMaskApply, and CSPadPixCoords.CSPadImageProducer:
