How to use Optical Character Recognition (OCR) with Python?

Optical Character Recognition (OCR) is a pivotal component of artificial intelligence and computer vision, facilitating the conversion of various digital text formats, such as PDFs and images, into machine-readable text. Emerging in the 1950s, OCR has evolved to become more intelligent and adaptable, supporting applications across industries like banking, healthcare, and law enforcement. The technology operates in three stages: image pre-processing, character extraction, and post-processing. Users can choose between open-source and cloud-based OCR engines, each offering distinct advantages. Open-source engines, such as pyTesseract and Keras-OCR, are cost-effective and customizable, while cloud engines like those from Google and Microsoft offer robust performance and scalability but at a cost. Eden AI offers a unified API that simplifies the integration of multiple OCR providers, allowing users to switch between them seamlessly based on performance needs, while ensuring data security and compliance with privacy regulations.
