Operations | Randomization |
|---|---|
Field of view | 8, 10, 20, 30, 40 angstroms |
Rotation | 0°–90° with 15° intervals |
Background | Constant, linear ramp, non-linear patterns |
Shot and scan noise | The shot and scan noise level is randomized |
Nanoparticle shape | The distance of the 111 facets have been randomized in the dataset |
Position offset | Randomized |
