Examples for Package ImgAlgos
Example for Module ImgAlgos::ImgPeakFinder
- This algorithm consumes ~15 ms/event on psana0101 for full Opal1000 (1024x1024) camera image.
- Smearing algorithm use a "safety margin" which is currently set to 10 pixels (offset from each boarder of the full image size).
...
- raw image,
- 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,
- smeared image,
- raw image with found peaks (marked by the red circles)
- zoom of the previous plot.

Example for Module ImgAlgos::CSPadArrAverage
Example of the configuration file for evaluation of pedestals:
...
Images of the CSPad arrays for averaged and rms values, respectively, in one of the CXI runs:
...
Example for Module ImgAlgos::CSPadBkgdSubtract
...
The file with the background array, bkgd_fname, was obtained by averaging 1000 events using module CSPadArrAverage. Subtraction is done with normalization for norm_sector=0.
Event image and pixel amplitude spectrum before and after the background subtraction are shown in plots:
Other event with better subtracted background:
