What did I do this week?

During my firs week, I developed user-defined function (UDF) for "crystallinity mapping" in LiberTEM for phase change materials and wrote some tests. This UDF helps to easily distinguish the amorphous and crystalline regions of the specimen.

The data which can be processed with the UDF is 4D-STEM datasets (2D scan domain and 2D detector domain). The algorithm I used is based on Integration over a ring of frames in Fourier space after deleting of outliers and frames preprocessing.

What is coming up next?

Implementing of a UDF for feature vector forming based on blob (non-zero order diffraction peaks) finding, this feature vector can be used for region clustering

Did you get stuck anywhere?

No specific problems appeared, just lack of experience with Github could make me a little slower.
