What is OCR (Optical Character Recognition)?

Evolving digital images into structured, editable, searchable text databases.

💡 Direct Answer: What is OCR?

Optical Character Recognition (OCR) is an advanced computer vision technology that automatically scans visual elements of printed, handwritten, or typed text inside digital images (like JPG, PNG, WEBP, or scanned PDF documents) and translates them into machine-encoded, fully editable, and searchable digital text data.

How Does the OCR Pipeline Work?

Modern AI OCR platforms convert images into raw text strings through a deterministic 4-stage pipeline:

⚙️

1. Preprocessing

Adjusting resolution, applying grayscale filters, and amplifying contrast to isolate character boundaries cleanly.

🔍

2. Feature Extraction

Analyzing strokes, loops, intersection nodes, and baseline offsets to identify distinct character glyphs.

🧠

3. Neural Scoring

Using trained neural network models (such as LSTM) to predict and map words based on context dictionary structures.
