 ## Introduction. 
 
 Kymographs are a very useful technique in bioimage analysis, that allow for visually following particles even  in data where they are very faint in a noisy background. A moving object drown in noise and background  signal could be become barely visible in the source image. In a kymograph its movement often becomes salient,  and easier to analyze.
