In the summer of 2018 I assisted with research through the NDnanotechnology Undergraduate Research Fellowship (NURF). Dr. Sergei Rouvimov lead a project that intends to optimize transmission electron microscope image data and quality. I was tasked with writing scripts in MATLAB and processing images using ImageJ software. A transmission electron microscope image looks like this:
Here is a link to the formal report for this research project.
The abstract of the project:
Transmission electron microscopy is one of most advanced metrologies in materials science, and the fast and accurate analysis of TEM data is a key for success in delivery of novel results. This research focuses on developing scripts written in MATLAB to process images and analytical data to get the most accurate results in TEM using periodicity vectors and an intensity averaging algorithm.
Here is one of our results, with the left hand image taken pre-processing and the right being an image sent through our algorithm:
