What are masking techniques?

Masking techniques explained

Masking techniques are methods used to hide or obscure sensitive regions of an image or video so that individuals cannot be identified. Common approaches include blurring, pixelation, solid-color boxes, and replacing a region with a custom overlay.

The right technique depends on the goal: irreversible masking destroys the underlying detail so it cannot be recovered, while lighter effects may still leave traces. Gallio PRO applies irreversible masking to faces and license plates, with options for blur, solid fill, or a custom image, and rectangular or rounded shapes.
