title: Microorganism track reconstruction: an image processing approach.
abstract: This paper presents an automatic system for the analysis of microorganism behaviour. The movements of free swimming microorganisms are videotaped by means of a television camera mounted on a microscope. The analysis is performed off-line by digitizing the video signal through the use of an image processor unit. Microorganism tracks are reconstructed spatially and chronologically by means of image processing techniques. From these tracks cell movement parameters are obtained. The results of our experiment in testing photoinduced movements follow.
