Figure 2
Image processing for the automesh algorithm. A series of images are taken 30° apart; examples are shown at 0° (a) and 90° (b). The background is then subtracted (c) and thresholding is used to detect the edges of the sample mount (d). The edges are then measured as a function of ω and pixels in order to determine the maximum and minimum ω orientations (e) and an area is selected for the mesh scan (f).
