Image Obfuscation

Techniques applied to images to obscure or remove sensitive visual information before sharing or processing, such as blurring, pixelation, edge filtering, or masking regions of an image. In accessibility contexts, image obfuscation is important for privacy-preserving assistive technologies that use cameras or crowdsourcing to help users understand their visual environment, such as remote sighted assistance services. Balancing privacy protection with the need to provide enough visual information for accurate scene description is a key design challenge.
