I need to quantify the threshold of the green color in the attached image to remove everything around it.
I started with something like this:
imshow(img(:,:,1))
[x1, y1] = ginput(1)
buffer = 1.5
img = buffer * (round(x1), round(y1) )

If you have the Image Processing toolbox installed, I would use the Color Thresholder app in MATLAB. I would then export the results to the workspace, and import that into the image viewer app to make measurements.
