Energy minimization for image focus volume in shape from focus

作者:

Highlights:

• Most of the shape from focus techniques optimize focus volume without considering any additional structural prior, and it leads to poor results.

• It has been proposed to use structural similarity between image sequence and focus volume as a structural prior for the enhancement of focus volume.

• An energy function has been proposed that consists of data fidelity, smoothness and structural similarity terms.

• Solution of 3D energy minimization problem has been approximated through a series of simple 1D subproblems.
