I am trying to measure intensity for two pictures by simply using two modules in a pipeline: LoadSingleImage, followed by MeasureImageIntensity. Strangely, two pictures with obvious different intensity by naked eys (see the attached pictures), resulted in almost same intensity from CP for either total intensity or mean intensity. Did I do anything wroing when measuring the intensity? By the way, the two pictures were taken with the same exposure time, so I assume that the value for background should be same as well.
Thank you for your help.
