Hi everyone,

I'm trying to measure the area and diameter of rings of dye (from evaporated water). After thresholding, the image looks the one below. How can I calculate the total area inside the circle? It seems like using "analyze particles" will only give me the total area of thresholded spaces within the particle. Thanks in advance
