Image J is a useful tool but like all other tools it has its drawbacks; which was discovered when examining selected pictures. There are limitations on what can be counted and how it will be counted. Even with this shortcoming the program is fantastic if inside certain parameters.

The source of the image is:

The strategy used for analysis was counting

Data:

ImageJSummarybloodcells

Inferences that can me made from the count could be the number of cancer cells in a blood smear. If this is indeed a smear. If it isn’t, the picture can still give the number of cells present by counting the nuclei present in the given space.
