AcroForm — Sozluk

The standard interactive form technology in PDF documents, supporting text fields, checkboxes, radio buttons, and digital signatures.

Teknik Detay

AcroForm works by analyzing pixel patterns in scanned or photographed text. Modern OCR engines like Tesseract use neural networks (LSTM architectures) trained on millions of character samples across hundreds of languages. The process involves binarization, skew correction, line segmentation, word segmentation, and character classification. Post-processing with language models and dictionaries improves accuracy beyond raw character recognition, typically achieving 95-99% accuracy on clean printed text.
