How to increase the quality of images of periodic structures

The examples of usage Find structure element function will be collected here. The detailed explanation on how this function works can be found in its description. It gives a very powerful tool to improve the image of periodic structures with molecular or atomic resolution, but requires fine-tuning of parameters. If you are unable to successfully use the function for your own images, we hope that the examples given here and indicating the values ​​of the parameters will assist you.

Example 1

Parameters values:

  • Level = 0
  • Locality = Neighborhood
    • Radius = 100 px
  • Dilate intermediate results = No
  • Accumulator
    • Width = 1024 px
    • Height = 1024 px

Example 2

An image of moire pattern on HOPG, obtained in STM.

Parameters values:

  • Level = 0,003
  • Locality = Structure element
  • Dilate intermediate results = Yes
    • Radius = 2 nm
  • Accumulator
    • Width = 512 px
    • Height = 512 px

Example 3

An image of dodecilamin film on HOPG, obtained in STM.

Parameters values:

  • Level = 0
  • Locality = Neighborhood
    • Radius = 3 nm
  • Dilate intermediate results = No
  • Accumulator
    • Width = 1024 px
    • Height = 1024 px
