    摘要： A method for observing biological species (CB) on a culture medium (MC) contained in a container having at least one translucent face (CP, BU), the method comprising the steps consisting of: a) directing a light beam (FL) onto one portion of said translucent face, so as to define at least one illuminated region (M1) and at least one non-illuminated region (MO) of said face; and b) acquiring an image of a portion (M2) of the surface of said culture medium illuminated by said light beam, the acquisition being carried out through said or at least one of said non-illuminated regions (MO) of said translucent face and along an optical acquisition axis forming a non-zero angle (a) with the direction of propagation of said light beam.

    摘要： A method for defining an isolation area around an object of interest in a cell culture vessel, the method comprising the steps of: - obtaining one or more images of the cell culture vessel using one or more of a plurality of illumination sources, each illumination source being capable of illuminating the vessel from a different direction; - selecting an image or combination of images for further processing; - applying a circular object detection transformation to identify one or more objects of interest being substantially circular objects in the cell culture vessel, which circular objects of interest are representative of isolated colonies in the cell culture vessel and determining the center of an object of interest; - applying a binarizing step to obtain a binarized image of the object of interest and other objects, wherein the center of the binarized image corresponds to the center of the object of interest; - iteratively forming concentric circles with increasing radius, wherein the concentric circles are centered on the center of the binarized image; - identifying coronas, wherein a corona is delimited by two circles having successive radius values; - for each corona: determining the presence and the location of any other object located in the corona to determine the presence and the location of other objects; - determining a clearance angle defining an angular sector free of other objects around the object of interest to define the isolation area around the object of interest.
