Abstract: A retail checkout system decodes machine-readable indicia from a composite image frame produced from a sequence of captured image frames. Different regions in the composite image are derived from different ones of the image frames in the captured sequence. Another embodiment generates a composite image frame from image frames captured with different camera focus settings. Still other embodiments concern neural networks, including their training to segment different items presented on a retail checkout surface. Other neural network embodiments discern on which of two items a machine readable indicia appears, when the visual context is ambiguous. A variety of other features and arrangements are also detailed.
