Abstract:
An activity recognition device comprises a port configured to receive a video stream from a video source for a first object and a second object; a memory configured to store instructions and image frames of the video stream; and one or more processors, wherein the one or more processors execute the instructions stored in the memory, the one or more processors configured to: select portions of the image frames based on presence of the first object; determine areas within the portions of image frames, wherein locations of the first object in the video frames are bounded by the determined areas; determine motion of the first object and locations of a second object within the areas of the image frames; and identify an activity according to the determined motion and locations of the second object, and generate an alert according to the identified activity.

Claim (Index 18):
The method of  claim 17 , determining areas within the portions of the image frames that bound locations of the first object includes:\n receiving a first image frame and a subsequent second image frame of the video stream; determining a similarity score between a first windowed portion of the first image frame and the first windowed portion of the second image frame, wherein the location of the first object is positioned in the first windowed portion of the image frames; omitting processing of the first windowed portion of the second image frame when the similarity score is greater than a specified similarity threshold; and when the similarity score is less than the specified similarity threshold, triggering detection of the first object in the second image frame to generate a second windowed portion of the image frames more likely to include the first object than other portions of the image frames, and including the second windowed portion in the determined areas.
