You might check some morphological operations you could perform on the image such as imfill and imdilate

To find the actual boundary, invert, fill, and sum

binaryImage = imfill(~binaryImage, 'holes');
numPixels = sum(binaryImage(:));

If you want a smooth boundary, you need to use activecontour(), like in my attached demo.

MATLAB: Smoothen 3d surf plot

num_segments = 100;   %divide the range into this many pieces
minx = min(x);
maxx = max(x);
miny = min(y);
maxy = max(y);
smoothx = linspace(minx, maxx, num_segments+1);
smoothy = linspace(miny, maxy, num_segments+1);
smoothz = interp2( x, y, z.', smoothx.', smoothy );
surf(smoothy, smoothx, smoothz);
