Title
(EN) IMAGE ANALYSIS OF HETEROGENEOUS MIXTURES
(FR) ANALYSE D'IMAGES DE MELANGES HETEROGENES
Abstract
(EN) A system for analyzing a plurality of samples (202) containing a dispersion of one or more incompletely miscible components in a continuous fluid phase comprises a vial receptacle located at a first location, an image capturing device (102) directed at the first location, a light source (112) directed at the first location, and a programmable processor (124) operatively coupled to the image capturing device and configured to detect a behavior in a captured image of a sample. The programmable processor defines regions of interest in a captured image, generates an intensity profile for each region of interest, and detects the behavior based on the intensity profile. The programmable processor defines the regions of interest by detecting a sample boundary in a captured image and defining a region within the sample boundary. The programmable processor detects behavior by calculating a Laplacian or a derivative of the intensity profile for the region.
(FR) La présente invention a trait à un système permettant l'analyse d'une pluralité d'échantillons (202) contenant une dispersion d'un ou de plusieurs constituants miscibles de manière incomplète dans une phase fluide continue comportant un réceptacle de type flacon situé à un premier emplacement, un dispositif de capture d'images (102) orienté vers le premier emplacement, une source lumineuse (112) dirigée vers le premier emplacement, et un processeur programmable (124) relié en fonctionnement au dispositif de capture d'images et configuré à détecter un comportement dans l'image captée d'un échantillon. Le processeur programmable définit des régions d'intérêt dans une image captée, génère un profil d'intensité pour chaque région d'intérêt, et détecte le comportement en fonction du profil d'intensité. Le processeur programmable définit des régions d'intérêt par la détection d'une limite d'échantillon dans une image captée et la définition d'une région au sein de la limite d'échantillon. Le processeur programmable détecte le comportement par le calcul d'un laplacien ou d'une dérivée du profil d'intensité pour la région.
