Abstract
This chapter proposes a new approach to recover 3-D shape from a Scanning Electron Microscope (SEM) image. When an SEM image is used to recover 3-D shape, one can apply the algorithm based on the solving the Eikonal equation with Fast Marching Method (FMM). However, when the oblique light source image is observed, the correct shape cannot be obtained by the usual one-pass FMM. The approach proposes a method to modify the original SEM image with intensity modification by introducing a Neural Network (NN). Correct 3-D shape could be obtained using FMM and NN learning without iterations. The proposed approach is demonstrated through computer simulation and validate through experiment.
