Developer Diary: Enabling secure sharing of personal memories

In our previous work [1, 2, 3], we compared first-person-view lifelog images – e.g., images taken using Narrative Clip devices – with third-person-view lifelog images – e.g., images captured by fixed infrastructure cameras. First-person view images usually provide a very particular vantage point, and as such may miss many things: camera lenses may get covered by clothes or hair, or may simply face the wrong way due to the way they are “mounted” on the body (e.g., with a clip). Even if an unobstructed view can be had, a first-person-view may only show a very small part of the scene, e.g., potentially never showing a person that sits right next to us. Images from fixed infrastructure cameras can compensate for such shortage: their high vantage point usually allows them to captures comprehensive scenes, completely unobstructed. Alternatively, a first-person-view image from another person may equally offer an interesting alternative to my own capture. These considerations prompted us to investigate the best way to combine first-person-view and third-person-view images in RECALL to reconstruct a better representation of a previous experience.
