Collab --
In the attached worksheet, I am attempting to fit an ellipse to a blob. I believe that the fitting orientation is correct, but it appears that my scaling is somehow off. I can calculate the area three ways -- pixels in the blob, using ellipse semi-axes, and integrating the function (but how?) -- and I would expect all of these values to be similar. From visual inspection, they are not. What am I missing?
Apologies in advance if this is a re-post -- I tried to submit yesterday and got a message that a moderator had to approve it first. I have never seen that message before and it has now been 24 hours, so I suspect that the original post may be in the ether, but I'm not sure....
