Assignee: AMAZON TECHNOLOGIES, INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 7:
8. A computing system, comprising:
one or more processors; and
a memory storing program instructions that when executed by the one or more processors cause the one or more processors to at least:
receive a first image data obtained at a first time and representative of an inventory location;
receive a second image data obtained at a second time and representative of the inventory location;
receive a third image data obtained at a third time and representative of the inventory location;
receive a fourth image data obtained at a fourth time and representative of the inventory location;
generate a first motion extracted image by at least:
comparing the first image data with the second image data to determine a first pixel of the first image data corresponding to an object that has moved in position between the first time and the second time;
extracting the first pixel; and
including at least a first portion of a baseline image to replace the extracted first pixel;

generate a second motion extracted image by at least:
comparing the third image data with the fourth image data to determine a second pixel of the third image data corresponding to an object that has moved in position between the third time and the fourth time;
extracting the second pixel; and
including at least a second portion of the baseline image to replace the extracted second pixel;

compare the first motion extracted image and the second motion extracted image to determine a difference between the first motion extracted image and the second motion extracted image, wherein the difference is determined based at least in part on a depth value difference between one or more pixels of the first motion extracted image and one or more pixels of the second motion extracted image; and
in response to a determination of the difference between the first motion extracted image and the second motion extracted image, generate an event notification indicative of an event.
