a The FLA workflow and the role of the proposed solutions. b DeepColony hierarchical architecture of the operational and decision-making processes. c Example of “enumeration map” (level 0 output) where the cardinality of colony aggregates is indicated with colours and numbers. An “X” appears on colonies discarded because they are located in colour distortion areas. d Example (on the same plate) of selected “good colonies” (level 1 output) with their presumptive ID (level 2 output). An “X” appears on colonies discarded because they are not single or too close to the plate border or to confluence areas. Detected species Si are indicated for each colony with colours and corresponding legend. e Outputs of level 3 and 4 are shown on the same plate. Gi refers to species ID updated after similarity-driven contextual grouping, while subsequent clinical relevance interpretation indicates a significant mixed flora plate, where best colonies eligible for picking are indicated with arrows. f CNN architecture for single colony presumptive ID (red box at level 2). g “Siamese CNN” scheme (red box at level 3) for contextual ID.
