Assignee: SMARTTHINGS, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 15:
16. A smart camera device, the smart camera device comprising:
a processor; and
a memory storage device, the memory storage device storing instructions that, when executed by the processor, cause the smart camera device to:
receive compressed video data;
extract macroblocks and motion vectors for a plurality of frames in the compressed video data;
identify frame-level features for each of the plurality of frames based on the macroblocks and the motion vectors;
calculate similarity features for each of the identified frame-level features based on the frame-level features identified in consecutive frames;
predict motion for each of the plurality of frames by providing the frame-level features and the similarity features into a model trained to detect motion; and
predict event boundaries in the compressed video data by providing the frame-level features into a second model trained to identify event boundaries.
