Detection of partially motion-blurred video frames

A system comprising:

• a processor;
• and
• a non-transitory computer-readable medium coupled to the processor, wherein the processor is configured to execute computer program code stored in the non-transitory computer-readable medium and thereby perform operations comprising:
• identifying a plurality of feature points within a video clip having a plurality of video frames, wherein a feature point can be associated with any object within the video clip;
• calculating a speed of each of the plurality of feature points within the video clip;
• determining, based on the speed of each of the plurality of feature points, a collective speed of the plurality of feature points for each video frame of the plurality of video frames;
• comparing a selection factor to a selection threshold for each video frame, wherein the selection factor is based at least in part on the collective speed of the plurality of feature points;
• and
• selecting at least one video frame from within the video clip based on the comparing of the selection factor to the selection threshold.

A non-transitory computer-readable medium storing program code executable by a processor to perform operations, the operations comprising:

• identifying a plurality of feature points within a video clip having a plurality of video frames, wherein a feature point can be associated with any object within the video clip;
• calculating a speed of each of the plurality of feature points within the video clip relative to frame boundaries over the course of at least two of the plurality of video frames;
• determining, based on the speed of each of the plurality of feature points, a collective speed of the plurality of feature points for each video frame of the plurality of video frames;
• comparing a selection factor to a selection threshold for each video frame, wherein the selection factor is based at least in part on the collective speed of the plurality of feature points;
• and
• selecting at least one video frame from within the video clip based on the comparing of the selection factor to the selection threshold.
