Abstract
(EN)
The invention concerns a method for analysing the cellular contractions of cells, comprising: - Recording a sequence of images of the cells, comprising a first image (10) and a second image (20). It is essentially characterised by: - Determining the position of remarkable points (11) in the first image (10), - Determining the position of these same remarkable points (11) in the second image (20), And, for at least one remarkable point of the first image (10): - Establishing a correspondence between the remarkable point (11) of the first image (10) and a remarkable point (11) of the second image (20), and - Determining the movement of the remarkable point (11) between the first (10) and the second image (20), by comparing the position of the remarkable point (11) of the first image (10) and the position of the corresponding remarkable point (11) of the second image (20).

L'invention concerne un procédé d'analyse des contractions cellulaires de cellules, comprenant : - Enregistrer une séquence d'images desdites cellules, comprenant une première image (10) et une deuxième image (20). Il est essentiellement caractérisé par : - Déterminer la position de points remarquables (11) sur la première image (10), - Déterminer la position de ces mêmes points remarquables (11) sur la deuxième image (20), Et pour au moins un point remarquable de la première image (10) : - Etablir une correspondance entre ledit point remarquable (11) de la première image (10) et un point remarquable (11) de la deuxième image (20), et - Déterminer le déplacement dudit point remarquable (11) entre la première (10) et la deuxième image (20), par comparaison de la position dudit point remarquable (11) de la première image (10) et la position dudit point remarquable (11) correspondant de la deuxième image (20).
