Is the main goal here just to have a cool-looking file extension?
Why not use PNG’s built-in zTXt chunks to store metadata? That seems like a more standard and less fragile approach.
I can see the case for using LSB steganography to watermark or cryptographically sign an image—but using it to embed all the metadata you're describing is likely to introduce a lot of visual noise.
Also worth considering: this approach could be used to poison models by embedding deliberately misleading metadata. Depending on your perspective, that might be a feature or a bug.
So, is there anywhere that indicates that the github codebase (under the apache license) @ https://github.com/OpenNI/OpenNI2 is also going to be scuttled? Or just the website?
