Area of Science:

  • Computer Vision
  • Image Processing
  • 3D Reconstruction

Background:

  • Depth From Focus (DFF) techniques are crucial for 3D scene reconstruction.
  • Existing focus measures face ambiguity issues, especially with occlusions.
  • Handling depth discontinuities and varying window sizes remains a challenge in DFF.

Purpose of the Study:

  • To propose a novel focus measurement method for Depth From Focus (DFF).
  • To address the focus measure ambiguity problem in the presence of occlusions.
  • To effectively handle depth discontinuities and allow for robust depth estimation.

Main Methods:

  • Utilizes an all-focused image to resolve focus measure ambiguity.
  • Employs adaptively shaped and weighted support windows for discontinuity handling.
