Patent attributes
Various examples are directed to systems and methods for detection motion in video data. An image processor may receive video data. A first frame and a second frame may describe a plurality of pixel locations. The second frame may be positioned after the first frame in the frame sequence. The image processor may determine that a first subset of pixel locations from the plurality of pixel locations differ by less than a threshold amount between frames for at least a threshold number of frames in the frame sequence prior to the first frame. The image processor may identify from the first subset of pixel locations, a second subset of pixel locations that differ by more than the threshold amount between the first frame and the second frame and determine that a number of pixel locations in the second subset of pixel locations is greater than a motion pixel threshold.
