Low-cost multi-camera object matching

We propose an object matching approach aimed at smartphone cameras that exploits the well-known concept of local sets of features for object representation. We also enable the temporal alignment of cameras by exploiting the frames of detected objects to group objects appeared in the same time interval for the assignment within each camera. The proposed approach does not need training thus making it suitable for matching during short temporal intervals. We use both outdoor and indoor datasets for the evaluation, and show that the proposed method reduces up to 95% the amount of information to be stored and communicated.
