Adaptive motion instability detection in video

摘要

One or more apparatus and method for adaptively detecting motion instability in video. In embodiments, video stabilization is predicated on adaptive detection of motion instability. Adaptive motion instability detection may entail determining an initial motion instability state associated with a plurality of video frames. Subsequent transitions of the instability state may be detected by comparing a first level of instability associated with a first plurality of the frames to a second level of instability associated with a second plurality of the frames. Image stabilization of received video frames may be toggled first based on the initial instability state, and thereafter based on detected changes in the instability state. Output video frames, which may be stabilized or non-stabilized, may then be stored to a memory. In certain embodiments, video motion instability is scored based on a probability distribution of video frame motion jitter values.

1. A computer-implemented video processing method, comprising:
receiving video frames; determining an initial state of motion instability associated with a plurality of the frames; monitoring for a motion instability state transition by comparing a first level of instability associated with a first plurality of the frames with a second level of instability associated with a second plurality of the frames; toggling image stabilization of received video frames based on the initial state of motion instability, and based on the motion instability state transition monitoring, wherein the toggling further comprises:
applying motion stabilization to received video frames in response to an initial level of instability satisfying a first threshold, and until a change between the first and second levels of instability satisfies a second threshold; orbypassing motion stabilization in response to the initial level of instability failing to satisfy the first threshold, and until a change between the first and second levels of instability satisfies the second threshold; and storing stabilized or non-stabilized video frames to a memory.
