Nanocrystal segmentation in SPED data #28

Closed tinabe closed 4 years ago

tinabe commented 4 years ago

A notebook was added that demonstrates nanocrystal segmentation on a SPED dataset obtained from partly overlapping MgO cubes. Two methods for segmentation are demonstrated based on i) virtual dark field (VDF) imaging and ii) non-negative matrix factorisation (NMF). Watershed segmentation is performed on individual VDF images and loading maps to separate out single crystals. Correlation and summation of VDF image segments and loading maps is also performed. The necessary pre-processing is also demonstrated.
