Classification: CPC G  H | IPC G  H

Claim 11:
12. A surveillance data processing system comprising one or more hardware computing devices storing computer program instructions that, upon execution, cause the one or more hardware computing devices to:
receive a video stream comprising image data captured at a first time by a surveillance device, the image data representing a surveillance area visible to the surveillance device at the first time;
determine, based at least in part on the image data, that a first tag is present in the surveillance area at the first time, wherein the first tag is not a unique identifier of any specific object present in the surveillance area;
identify a first target appearing in the image data, the first target representing a first object bearing the first tag;
identify a first portion of the image data that is associated with the first target;
determine that the first object is at a first location in the surveillance area at the first time;
determine that the first portion of the image data overlaps, at an overlapping portion, a second portion of the image data depicting a second object present at a second location in the surveillance area at the first time;
determine that the second location is closer than the first location to the surveillance device;
transform a target portion of the image data, the target portion comprising the first portion excluding the overlapping portion, using modification data associated with the first tag to produce surveillance image data; and
send a modified surveillance video stream comprising the surveillance image data to a display device in communication with the one or more hardware computing devices.
