Open the Cell Counter plugin and the image/stack you want to count (if the Cell Counter plugin is already open you don’t need to open a new instance). Measure…: Measures the pixel value at each marker and displays a result window showing: Type - Slice - X coordinate - Y coordinate - Pixel Value.Export Image: Makes a copy of the counter image with the markers written on it (only the current slice is copied in case of a stack).
