Well, digital zoom is doesn't add anything. Still a questionable defense but if you search on Google for "pinch to zoom interpolation" you will find countless news articles to exactly this topic.
I ask myself why do I even find these articles? Has nobody ever searched for interpolation algorithm for Apple? Results like this make me feel I live in FakeWorld®. Arstechnica has become abysmal, but a lot of other tech sites too.
Not that this is relevant to the argument of the defense at all. It is complete bollocks, but I still would like to know what interpolation method the zoom of the standard image app on iOS uses (standard, not multiple lens magic). Is this some corporate secret from Apple and nobody knows? At least the articles could have looked it up.
Aside from that there is merit to not resample an image and look at the "raw" data. Image forensics is regulated I believe and I don't know if they would accept Apple zoom either to be honest. That would be interesting to ask a professional, perhaps a real journalist could help here?
I think the case if high profile enough that you can send someone to buy the largest TV one could find.
- pbaka 5y agoIn general you are right, it is not relevant, except in this case the area in question was about 30 pixels square in the original badly lit night footage. Here are the picture sin question : https://preview.redd.it/ik22sbz2e6z71.png?width=2170&format=png&auto=webp&s=5be69f58b5e0c58c1d9631df21340255a799f6d7 https://preview.redd.it/ik22sbz2e6z71.png?width=2170&format=... With an area that small in those conditions, you'd rather not use any algorithmic interpolation or machine learning in a judicial setting. Quoting another commenter here : "Expert witness said he had no way to know and never compared his work to original, [...] if he ever held his enhanced image next to original to see if they matched. Expert said no I never did that."
