Measuring area fraction in a Weka classifed image

#1

Hi, I’m a new user to ImageJ, and I’m trying to measure the percent cover of lichen in images of our plots. I have already used the Trainable Weka Segmentation to classify the image with 2 classes, but am having a hard time measuring the area fraction of each pixel type. If I use the measure tool, is that measuring class 1 area or class 2? Is there a different way to measure the area of each class? Thanks!
