Abstract
A device for detecting objects includes a vessel intended to contain the objects. A sensor is configured to capture at least one image of the vessel. A processing device is configured to process at least one captured image by detecting objects of the at least one captured image, extracting characteristics of each detected object, and generating a list of the characteristics of each detected object. A memory stores the generated list, the memory also configured to store a first reference list of object characteristics. The processing device further generates a second list of characteristics from a captured image. The characteristics of each object of the second list are compared with, respectively, the characteristics of each object of the reference list.
