Systems and methods for facilitating video fingerprinting using local descriptors

A non-transitory computer-readable storage medium storing computer-executable instructions that, in response to execution, cause a device comprising a processor to perform operations, comprising:

• determining one or more local descriptors for one or more frames of the video;
• quantizing the one or more local descriptors to generate first frame information;
• and
• computing a subfingerprint associated with a snippet of the video, wherein the computing the subfingerprint comprises computing a first hash based on accumulated first frame information over the snippet of the video.

A method, comprising:

• employing a microprocessor to execute computer executable components stored within a memory to perform the following:
• generating one or more values for at least one frame of information based on first frame information, wherein the first frame information comprises quantized one or more local descriptors for the at least one frame of a video;
• accumulating additional first frame information over a snippet of the video, wherein the snippet comprises the at least one frame and one or more additional frames of the video within a defined duration of time;
• and
• computing a subfingerprint associated with the snippet based on a hash associated with the accumulated first frame information over the snippet.

A non-transitory computer-readable storage medium storing computer-executable instructions that, in response to execution, cause a device comprising a processor to perform operations, comprising:

• generating a first set of one or more local descriptors for at least one frame of a video;
• generating a second set of one or more local descriptors for a flipped version of the at least one frame of the video;
• quantizing the local descriptors of the first set and the second set to generate quantized local descriptors;
• appending, to one or more of the quantized local descriptors, an identifier of a part of a snippet of the video in which the one or more of the quantized local descriptors is located to generate a set of augmented quantized local descriptors;
• generating a histogram representing the set of augmented quantized local descriptors;
• and
• computing a subfingerprint for the video based at least on computing one or more hash values for the histogram.
