plot2txt
Plot2txt creates and manages API methods for performing analysis of images and other binary documents like audio, using a combination of computer vision, machine learning and traditional OCR. These algorithms run using Amazon Web Services (AWS) Lambda functions, overall providing a powerful means for creating highly scalable computer vision applications. Input is base64 encoded PNG or WAV files,…
