Abstract

L'invention concerne un procédé d'analyse d'un milieu par imagerie holographique et un système d'imagerie correspondant, dans lesquels une image (101) d'un échantillon de milieu présent dans une chambre d'observation illuminée par une source lumineuse est acquise par un capteur photosensible, le procédé étant caractérisé en ce qu'il comprend de plus, après chaque acquisition, une phase de détection de défauts utilisant les niveaux de gris de l'image acquise, cette phase de détection de défauts comprenant : une partition de l'image acquise (101) en un nombre prédéterminé N de vignettes (32, 33) ; l'évaluation pour chaque vignette et pour l'image entière d'un paramètre statistique caractérisant la distribution des niveaux de gris dans la vignette et dans l'image entière, respectivement ; le calcul d'un facteur d'alarme à partir des paramètres statistiques précédemment évalués ; la comparaison du facteur d'alarme obtenu à un seuil d'alarme prédéterminé et le classement de l'image acquise en image défectueuse ou valide selon le résultat de la comparaison précédente.The invention relates to a method for analyzing a medium by holographic imaging and to a corresponding imaging system, in which an image (101) of a sample of medium present in an observation chamber illuminated by a light source is acquired by a photosensitive sensor, the method being characterized in that it further comprises, after each acquisition, a defect detection phase using the gray levels of the acquired image, this defect detection phase comprising: a partition the acquired image (101) in a predetermined number N of thumbnails (32, 33); evaluating for each vignette and for the entire image a statistical parameter characterizing the distribution of the gray levels in the vignette and in the entire image, respectively; the calculation of an alarm factor from the statistical parameters previously evaluated; the comparison of the alarm factor obtained with a predetermined alarm threshold and the classification of the acquired image into a defective or valid image according to the result of the previous comparison.
