Depth Estimation Based on 3D Focus Measurement

Seong-O. Shim
Abstract—The technique to estimate depths of every object points from multiple images of same object acquired at different focus settings is called depth (or shape) from focus. The focus measurement at each pixel in image stack is important part for accurate depth map computation. The traditional focus measure operators compute focus (sharpness) value of each pixel from its neighbourhood. In this paper, we propose a focus measure based on three-dimensional gradients. Experimental results demonstrate that the accuracy of final depth map can be improved by applying the proposed method.

Index Terms—Depth from focus, focus measure, depth map, three-dimensional gradient.
