This paper introduces low-level operators in the context of detecting cylindrical axis in 3D images. Knowing the axis of a
cylinder is particularly useful since its location, length and curvature derive from this knowledge. This paper introduces
a new gradient-based optimal operator dedicated to accurate estimation of the direction toward the axis. The operator relies
on Finite Impulse Response filters. The approach is presented first in a 2D context, thus providing optimal gradient masks
for locating the center of circular objects. Then, a 3D extension is provided, allowing the exact estimation of the orientation
toward the axis of cylindrical objects when this axis coincides with one of the mask reference axes. Applied to more general
cylinders and to noisy data, the operator still provides accurate estimation and outperforms classical gradient operators. |
