How to calculate coordinate of binary iamges boundary??

My goal is calculate the amplitude and wavelength from the binary iamges.
To do so, I want to get the coordinates of boundary line from the binary iamges.
Now I'm making code using "bwtraceboundary" function.
If you have any good ideas, please share them.
Thanks

It looks like the boundary is pretty solid and you probably just want the top row, not the sides and bottom. So in that case I'd just scan your image to find the top row. If mask is your binary image:
[rows, columns] = size(mask);
topRows = nan(1, columns);
for col = 1 : columns
t = find(mask(:, col), 1, 'first')
if ~isempty(t)
topRows(col) = t;
end
end
