Abstract: A method for decoding a barcode included in at least one scan line into a string of decoded characters. The method includes for each of at least one barcode character set, establishing a validation threshold based, at least in part, on a degree of difference found among a respective set of reference barcode symbols employed in representing a respective set of reference characters included in the barcode character set with which the respective validation threshold is associated. Each detected barcode symbol is decoded into a decoded character for a corresponding character position in the string using a selected character set. A best-matching symbol is identified for the detected barcode symbol among the respective set of reference barcode symbols of the selected character set. A best-matched character that is represented by the best-matching symbol is validated as the decoded character using the respective validation threshold established for the selected character set.

Abstract: Peer-to-peer video streaming software that takes video from a host's Graphical Processing Unit (GPU), moves it to the encoder, manages the color conversions, moves the video into the networking software, and in turn manages the video on a client. This software also handles the inputs from the client and tells the host how to react to the client's inputs. In executing the video streaming, the host broadcasts and renders the video that is or will be streamed. It encodes the video frame with a hardware encoder that is part of the GPU to eliminate latency associated with transferring frames to the central processing unit (CPU). The host transmits compressed video and audio data to the client, and the client uses its hardware decoder and the video streaming software to render the video. The client sends mouse, keyboard, joystick, and controller signals to the host, which varies the bit rate based on the network connection.

Abstract: An automated checkout system modifies received images of machine-readable labels to improve the performance of a label detection model that the system uses to decode item identifiers encoded in the machine-readable labels. For example, the automated checkout system may transform subregions of an image of a machine-readable label to adjust for distortions in the image's depiction of the machine-readable label. Similarly, the automated checkout system may identify readable regions within received images of machine-readable labels and apply a label detection model to those readable regions. By modifying received images of machine-readable labels, these techniques improve on existing computer-vision technologies by allowing for the effective decoding of machine-readable labels based on real-world images using relatively clean training data.
