摘要： A medical device monitoring system and method extract information from screen images from medical device controllers, with a single OCR process invocation per screen image, despite critical information appearing in different screen locations, depending on which medical device controller's screen image is processed. For example, different software versions of the medical device controllers might display the same type of information in different screen locations. Copies of the critical screen information, one copy from each different screen location, are made in a mosaic image, and then the mosaic image is OCR processed to produce text results. Text is selectively extracted from the OCR text results, depending on contents of a selector field on the screen image, such as a software version number or a heart pump model identifier.

摘要： A non-transitory processor-readable medium stores instructions to be executed by a processor. The instructions cause the processor to receive a first trained machine learning model that generates a transcription based on a document. The instructions cause the processor to execute the first trained machine learning model and a second trained machine learning model to generate a refined transcription based on the transcription. The instructions cause the processor to execute a quality assurance program to generate a transcription score based on the document and the transcription. The instructions cause the processor to execute the quality assurance program to generate a refined transcription score based on the refined transcription and at least one of the document or the transcription. The at least one refined transcription score indicates an automation performance better than an automation performance for the at least one transcription score.

摘要： Described herein are systems, methods, and other techniques for training a generative adversarial network (GAN) to perform an image-to-image transformation for recognizing text. A pair of training images are provided to the GAN. The pair of training images include a training image containing a set of characters in handwritten form and a reference training image containing the set of characters in machine-recognizable form. The GAN includes a generator and a discriminator. The generated image is generated using the generator based on the training image. Update data is generated using the discriminator based on the generated image and the reference training image. The GAN is trained by modifying one or both of the generator and the discriminator using the update data.

摘要： Uređaj za očitavanje numeričkih podataka s mjerila rješava tehnički problem automatiziranog i daljinskog očitavanja stanja brojila s numeričkim podacima u slučajevima kada je ugradnja nekog drugog tipa brojila koje omogućava daljinsko ili automatizirano očitavanje neisplativo ili tehnički neizvedivo. Uređaj se sastoji od kamere (2) koja bilježi stanje alfanumeričkog brojčanika na mjerilu (1). Informacija o stanju brojčanika prenosi se putem kablova (3) na jedinicu za sabiranje i obradu podataka (4) koja pomoću specifičnog kompjuterskog programa obrađuje dobivenu informaciju i oblikuje je kao prikladan elektronički zapis u željenom formatu, te istu preko jedinice za predaju podataka, (5) prosljeđuje dalje prema korisniku. Koncentrator radijskih signala (8) prikuplja signale s više lokalnih sustava za očitavanje, pojačava i prosljeđuje signal prema prijemniku (9). Jedan od temeljnih prednosti uređaja je mogućnost njegovog korištenja bez posezanja u integritet postojećeg mjerila/brojila čime se narušavaju ranije ishodovana tipna odobrenja za korištenje.

摘要： A computer-implemented method for processing images of a document is disclosed. The method includes: displaying, on a display of an electronic device, a live view image of at least part of a document captured by a camera of the electronic device, the at least part of the document having imprinted thereon a plurality of data fields and corresponding data entry items, wherein displaying the live view image includes: receiving image data for a first image of the at least part of the document captured using the camera; extracting one or more of the data entry items from the document based on processing the first image; and displaying the extracted data entry items on the live view image of the at least part of the document, the extracted data entry items being displayed in annotation overlays on the live view image in association with representations of their respective corresponding data fields in the live view image. The method further includes displaying, on the display, a first user interface element concurrently with the live view image of the at least part of the document, the first user interface element being selectable to update a database record using the extracted data entry items.
