abstract = "Three-dimensional (3D) shape reconstruction is a
fundamental problem in machine vision applications.
Shape From Focus (SFF) is one of the passive optical
methods for 3D shape recovery that uses degree of focus
as a cue to estimate 3D shape. In this approach,
usually a single focus measure operator is applied to
measure the focus quality of each pixel in the image
sequence. However, the applicability of a single focus
measure is limited to estimate accurately the depth map
for diverse type of real objects. To address this
problem, we develop Optimal Composite Depth (OCD)
function through genetic programming (GP) for accurate
depth estimation. The OCD function is constructed by
optimally combining the primary information extracted
using one/or more focus measures. The genetically
developed composite function is then used to compute
the optimal depth map of objects. The performance of
the developed nonlinear function is investigated using
both the synthetic and the real world image sequences.
Experimental results demonstrate that the proposed
estimator is more useful in computing accurate depth
maps as compared to the existing SFF methods. Moreover,
it is found that the heterogeneous function is more
effective than homogeneous function.",
