The timing is about but right but it was definitely different work focused specifically on extracting the scene the subject of the photo was looking at.

I've hunted repeatedlty for a paper or similar covering the presentation and can only conclude that the presentation (and possibly one paragraph conference talk description that probably exists but that I've not been able to find) is likely the only "publication" of the work which is definitey a bummer.

Was it this one?

I remember seeing it that year...was an interesting read.

This one is even closer, but it looks like these researchers used a custom camera setup and the presentation I saw made a big point of the fact that they were doing the work using their existing consumer grade cameras and lenses (since the presenters worked for one of the big digital camera companies of the day)
