Data Analysis

The processing of large image data sets (as happens in LEEM movies) poses great challenges in terms of CPU usage and computation speed. Ideally, one wants to (quickly) load images into a 3D stack, onto which perform routine operations, such as extracting intensity profiles and integration in a ROI (region of interest). The IGOR PRO macro that I previously developed for this purpose is outdated, slow and difficult to maintain. I am currently re-writing it, to make it faster and more versatile, exploiting the capabilities of the most recent version of Igor Pro (6.XX). The main features of the macro are the use of ImageTransform and Matrix operations, that enable to save precious time during load data and analysis. In order to ease being tidy during processing, each image data set is saved into a dedicated datafolder.
