filename = 'https://www.mathworks.com/matlabcentral/answers/uploaded_files/1094395/image.jpeg';
img = imread(filename);
bw = im2bw(img);

imshow(bw)

props = regionprops(bw, 'Area', 'Centroid');

props

props = struct with fields:
        Area: 50890
    Centroid: [209.7235 135.0689]

Thanks a lot! I guess I was overthinking, this one's so easy!

The im2bw step is important here. jpeg files are almost always rgb files.
