PROCÉDÉS ET SYSTÈMES D'AMÉLIORATION DE BORD D'IMAGE BASÉE SUR L'APPRENTISSAGE POUR CERCLES SUPÉRIEURS DE TUBE D'ÉCHANTILLON

摘要

Methods for image-based detection of the tops of sample tubes used in an automated diagnostic analysis system may be based on a convolutional neural network to pre-process images of the sample tube tops to intensify the tube top circle edges while suppressing the edge response from other objects that may appear in the image. Edge maps generated by the methods may be used for various image-based sample tube analyses, categorizations, and/or characterizations of the sample tubes to control a robot in relationship to the sample tubes. Image processing and control apparatus configured to carry out the methods are also described, as are other aspects.
