===== How to increase the quality of images of periodic structures=====
The examples of usage [[..:processing:найти_структурный_элемент|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===
