H = surfheight(R, H0, N) computes the surface height H, given the
displacement field R, the mean height H0 and the refraction index N
(N=1.33 by default). The displacement field is obtained from the
correlation of a reference image (flat surface) and a distorted image.
H = surfheight(..., MODE) specifies the integration mode:
1 : small slope and arbitrary amplitude (by default)
2 : small slope and small amplitude
surfheight is based on INTGRAD2.M by J. D'Errico.
Example
r = loadvec('*.vc7');
h = surfheight(r, 10);
showscal(h);
