Introduction to text recognition with the Vision framework

Integrating modern optical character recognition capabilities into native iOS applications using Swift.

#2 about 5 min

Processing native image data with Vision framework request handlers

Handling document pipelines by connecting camera snapshots and image galleries to algorithmic request handlers.

#3 about 3 min

Implementing recognized text requests and handling candidate outputs

Generating specific code commands that return structured observation arrays for categorizing readable string alternatives.

#4 about 4 min

Trade-offs between fast and accurate text recognition levels

Balancing immediate asynchronous performance metrics with processor-heavy deep learning neural networks.

#5 about 4 min

Configuring custom lexicons for domain-specific text recognition accuracy

Improving string reading probability and logic by passing domain custom vocabularies into language transcription correctors.

#6 about 9 min

Demonstrating text recognition from books, business cards, and receipts

Seeing the framework independently capture real world variables across printed pages, contact cards, and bilingual sales receipts.
