.heic files | LinkedIn post by Finn Jäger

Did you know your iPhone .heic files are more than just a single image?

Update: I have made the code to extract all these images available here
https://lnkd.in/etSq-KuW
its python so it should work on windows/linux also compared to the switft implementations I have found so far

I was investigating how HDR Gain Maps are embedded into HEIF files by Apple on the iPhone – I wrote a extractor tool and found a bunch more auxiliary images – as expected a black and white gain map thats apparently rec709 encoded and a Display-P3 encoded? base image

But thats not all there also is a low res depth map and a handful of mattes (skin, hair, portaiteffects, “glasses” and a “teeth” matte)

Pretty interesting , I really want to try to merge them back to one image now.

This can be very useful for AI applications , where all this data is used – especially the depth map , nur sure if this is the trueDepth output or a ML generate depth map?
