Abstract
Cameras having storage fixtures within their fields of view are programmed to capture images and process the images to determine whether such images depict an interaction by an actor with one of the storage fixtures. If a camera determines that an actor is present within imaging data captured thereby, the camera generates feature tensors from images captured over a predetermined period of time and pools the feature tensors into features corresponding to locations of the respective storage units of the actor within such images. Cameras provide pooled features to a multi-camera system that processes the pooled features to determine whether an interaction occurred at a storage unit, and to update a record of items associated with the actor accordingly.
