Abstract: In-situ transmission electron microscopy (in-situ TEM) allows us to observe various phenomena at the nanoscale, such as particle agglomeration, oxidation and reduction, and electrodeposition. Because in-situ TEM examines the entire process, including intermediates, it can reveal the details of phenomena. Stimuli for in-situ TEM experiments can include heating, bias, stress, illumination, gas, liquid, cryo, and magnetic fields. However, an important point for in-situ TEM is the implantation of the target phenomena into the TEM reality, which is only available when the stimuli actively interact with the live processed information from the observed data. To proceed with live processing, two requirements should be solved: 1) establishing live data communication between the microscope, in-situ stimuli, and processing server, and 2) developing a fast image processing algorithm suitable for live processing. In this talk, I will show the second part, the current development of image processing method for in-situ TEM towards live processing. For live processing, processing speed is more important than processing quality. The datasets used for image processing method development are liquid phase in-situ TEM cases about electrodeposition. The principle is to extract the changes during the phenomena, so subtraction from reference image or previous time frame is the fast and effective way of visualization. I believe that these efforts can allow to investigate the nanoscale phenomena more actively.
