How does a Moka Pot work? 2D X-Ray video gives insights!

This sequence of X-Ray images shows how one of the most common Italian moka pots actually work! The sequence starts with a completely prepared moka pot (water in the bottom part, coffee in the middle and hot plate on). During the process the water starts to boil and the steam pressure pushes the hot water through the coffee into the bassin at the top of the pot. This video sequence and additional explanations can also be found on Wikipedia under: Wikipedia Moka pot english Wikipedia Moka pot german The data set contains: TIF-stack of the raw footage (sequence of X-Ray images) 3 artificially colored images in the beginning (Bottom), mid (Mid) and end (Top) of the process. The colored images are based on an image processing workflow which includes the time-derivative of the raw seqeunce, minima and maxima projections, HUE color-space transformation, etc.
