Optical Character Recognition (OCR) is a transformative technology that converts images of text into machine-readable text, facilitating the automation of data entry, document management, and accessibility for visually impaired individuals. The OCR process involves image acquisition, preprocessing, segmentation, feature extraction, character recognition, and post-processing. Recent advancements, particularly in deep learning and multi-modal models, have significantly enhanced OCR's accuracy and ability to handle complex scenarios, such as noisy images and handwritten text. Despite its benefits, OCR faces limitations, including challenges with complex backgrounds, various fonts, and handwritten text, and it often requires additional machine learning tools for structuring extracted data. Companies like Clarifai offer AI platforms that simplify the integration of OCR into applications, allowing developers to build intelligent text extraction systems and automate workflows effectively.
