lvfindtilt - find the least-squares best fit plane for an image
LIBRARY CALL
int lvfindtilt(
xvimage *image,
double *a,
double *b,
double *c)
INPUT
image - input xvimage structure
OUTPUT
a - the a coefficient of the plane
b - the b coefficient of the plane
c - the c coefficient of the plane.
RETURN VALUE
TRUE (1) on success, FALSE (0) otherwise
DESCRIPTION
This routine computes the least-squares best fit plane for
an image. The plane will be given by f(x,y)=Ax+By+C
with the tilt coefficients in inverse pixels.
