Detector sensitivity estimation with the coefficient of variation (cv)
Confocal detector sensitivity measurement by coefficient of variation (CV)
This macro calculates the coefficient of variation (CV, ratio of standard deviation to mean) of the intensity in the confocal image acquired in standardized conditions. CV is a good indicator of the overall sensitivity of the confocal detector and can be used for characterizing and comparing detectors inside one and across different confocal systems and specific spectral ranges. The detector with highest sensitivity has lowest CV value. The input for macro is two consecutive images, detailed measurement protocol is below.
This macro is inspired by work of Zucker: R.M. Zucker and O.Price, Cytometry 44:273–294 (2001). Big thanks to Kota Miura for helpful suggestions regarding the macro programming.
