## What it is
A Python library for embedding and extracting blind (invisible) watermarks in images using DWT-DCT-SVD transforms, with watermark recovery not requiring the original image. It provides both a Python API and a command-line interface with password-protected embedding.

## Use cases
- embed invisible watermarks in images to prove ownership
- extract a watermark from an image without the original
- add copyright protection to photos before publishing
- detect if an image was stolen from your collection
- batch watermark images from the command line
- hide a text message inside a picture

## When to choose
- you need robust invisible watermarks that survive compression and resizing
- you don't have access to the original image when extracting
- you want a simple pip-installable Python or CLI tool for image watermarking

## When to avoid
- you need visible overlay watermarks or logos on images
- you require watermarking for video or audio files
- you need cryptographically guaranteed tamper-proofing rather than steganographic marking

## Facets
- artifact type: library
- maturity: stable
- function: image-processing, security, cli
- domain: image-processing, security, privacy
- platform: python, windows, cli
