Generating synthetic frame features for sentinel frame matching

A method comprising:

• receiving, by a computing device, a first signature for a video that includes a plurality of frames, wherein the first signature is based on a first set of features;
• analyzing, by the computing device, the plurality of frames of the video using the first signature to identify a first set of frames from the plurality of frames that are defined as sentinel frames of the video, wherein the sentinel frames identify a transition from a first type of video content to a second type of video content;
• analyzing, by the computing device, the first set of frames to generate a second signature, the second signature including a second set of features that is different from the first set of features, wherein the analyzing the first set of frames to generate the second signature comprises:
• comparing a distance between the first signature and the second signature to a deviation threshold, and
• when the distance is within the deviation threshold, generating the second signature;
• and
• outputting, by the computing device, the second signature as a replacement for the first signature.

A non-transitory computer-readable storage medium containing instructions that, when executed, control a computer system to be configured for:

• receiving a first signature for a video that includes a plurality of frames, wherein the first signature is based on a first set of features;
• analyzing the plurality of frames of the video using the first signature to identify a first set of frames from the plurality of frames that are defined as sentinel frames of the video, wherein the sentinel frames identify a transition from a first type of video content to a second type of video content;
• analyzing the first set of frames to generate a second signature, the second signature including a second set of features that is different from the first set of features, wherein the analyzing the first set of frames to generate the second signature comprises:
• comparing a distance between the first signature and the second signature to a deviation threshold, and
• when the distance is within the deviation threshold, generating the second signature;
• and
• outputting the second signature as a replacement for the first signature.
