iat_normal_coords

[ NPOINTS, T ] = iat_normal_coords( POINTS )

iat_normal_coords implements the normalization of the coordinates in point set POINTS, such that their centroid is at the origin (0,0) and their mean distance from origin is sqrt(2). It is an essential preprocessing step before any transform estimation for better stability/accuracy.

Input arguments

POINTS The input set of points in homogeneous coordinates

Output arguments

NPOINTS The normalized set of points
T The normalization transform, so that NPOINTS = T*POINTS
