I'd think taking the average of the x and y values for each endpoint would do it:
xMiddle = (x1+x2)/2;
yMiddle = (y1+y2)/2;
or am I overlooking something?

Look at bwmorph()
epImage = bwmorph(skeletonImage, 'EndPoints');
bpImage = bwmorph(skeletonImage, 'BranchPoints');
[epRows, epColumns] = find(epImage); % Get location of end points.
hold on;
plot(epColumns, epRows, 'r.', 'MarkerSize', 30);
[bpRows, bpColumns] = find(bpImage); % Get location of branch points.
plot(bpColumns, bpRows, 'ro', 'MarkerSize', 40);
