Modern OCR systems are heavily based on machine learning, particularly for recognizing text in diverse fonts, sizes, and conditions. Traditional OCR methods relied on pattern matching and rule-based approaches, but these systems struggled with variability in text appearance or noisy backgrounds. Machine learning models, such as convolutional neural networks (CNNs), have revolutionized OCR by enabling systems to learn directly from data. These models are trained on large datasets of labeled text images to recognize characters and words under various conditions. For example, Google's Tesseract OCR engine incorporates machine learning to handle different languages and fonts effectively. Advanced OCR systems also use sequence models like Long Short-Term Memory (LSTM) networks for tasks like handwritten text recognition or processing sequential characters. By leveraging machine learning, OCR systems achieve high accuracy and robustness, making them suitable for real-world applications such as invoice processing, identity verification, and document digitization.
