Building an OCR System Using Runpod Serverless

Building an Optical Character Recognition (OCR) system using Runpod Serverless and pre-trained models from Hugging Face can automate the processing of receipts and invoices, transforming images into structured data and reducing manual data entry errors. The tutorial outlines a step-by-step process, including setting up a Runpod Serverless environment, deploying the OCR model, and writing an InvoiceProcessor class to convert images to base64 format for model inference. Users are guided on processing single or multiple images, examining output in JSON format, and generating PDF invoices using the ReportLab library. This approach streamlines workflows by converting extracted data into formatted invoices, offering potential extensions like enhancing error handling, customizing invoice templates, and integrating with accounting software. By completing this tutorial, users gain practical experience in OCR systems, paving the way for more advanced data extraction and document processing tasks.
