About:
Viz is a command-line utility designed to extract text from various visual sources including images, videos, QR codes, and barcodes. It leverages optical character recognition (OCR) and computer vision technologies to provide accurate text detection and retrieval. This tool is ideal for automating data extraction tasks where visual content needs to be converted into machine-readable text.

Key Features:

Supports OCR extraction from images and video frames
Decodes QR codes and various barcode formats
Command-line interface for easy automation and scripting
Cross-platform compatibility

Use Cases:

Extracting text from screenshots or scanned documents for data processing
Batch decoding QR codes or barcodes from image files
Automating text extraction from video content for analysis or subtitling

Alternatives:

tesseract – Tesseract is a powerful open-source OCR engine but lacks built-in QR/barcode decoding; Viz provides a more integrated solution for multiple visual data types.
zbarimg – zbarimg focuses specifically on barcode/QR decoding; Viz offers broader functionality including OCR for regular text.
