Publication number: 20230345115Abstract: A method and system of operating a microscopy system are disclosed. A first image first image of a sample acquired using a first imaging configuration is received. A second image is developed from the first image, wherein the second image is associated with a second imaging configuration. A sequence of image processing steps is applied to the first image to develop a first classification of first objects represented in the first image and to the second image to develop a second classification of second objects represented in the second image.
