Why should I use this image forensics tool?

This analysis tool helps you to find out which meta data like Exif, IPTC, XMP, ICC color profiles, GPS coordinates and Quantization tables are hidden in your images and photos.

This can be useful for security reasons in the field of forensics, but it can also help developers in the field of digital image processing to analyze what compression settings were used when generating the image (e.g. estimated JPEG quality) and how well the compression works (look for PNG compression view).

Also, for commercial sites, it can be useful to check the copyright and licensing notices that may have been placed in the images.

Image compression with AI

Wow! Google researchers have now proposed a new method that combines a standard autoencoder with a diffusion process to recover and add fine details discarded by the autoencoder. Interesting to see the possibilities AI opens up when compressing images.

How Should We Store AI Images? Google Researchers Propose an Image Compression Method Using Score-based Generative Models - MarkTechPost
MarkTechPostA year ago, generating realistic images with AI was a dream. We were impressed by seeing generated faces that resemble real ones, despite the majority of outputs having three eyes, two noses, etc. However, things changed quite rapidly with the release of diffusion models. Nowadays, it is difficult to distinguish an AI-generated image from a […]
