Hough transform

Hough transform

"Hough transform" is a method to transform a certain line in an image into one point. In analysis of lattice strain by CBED, the lattice strain is determined in such a way that the positions of experimental HOLZ lines are reproduced by computer simulation of the lines with changing lattice parameters. In this determination, if the HOLZ lines are expressed as points (Cartesian coordinates) by the Hough transform, computer programming for fitting can be facilitated.
