Leveraging Audio Matches to Improve Visual Matching Recall Between Video Content Items

A system, comprising:

• one or more memories;
• and
• one or more processors, the one or more processors configured to execute instructions stored in the one or more memories to:
• perform an audio matching between a first video content item and a second video content item to identify a matching audio segment;
• define a visual search space within the first video content item and the second video content item based on the identified matching audio segment;
• perform a visual matching between the first video content item and the second video content item within the visual search space;
• and
• determine whether a match exists between the first video content item and the second video content item based on the visual matching.

One or more non-transitory computer readable media storing instructions operable to cause one or more processors to perform operations comprising:

• performing an audio matching between a first video content item and a second video content item to identify a matching audio segment;
• generating visual similarity values between portions of the first video content item and the second video content item corresponding to the matching audio segment;
• selecting a top predetermined percentage of highest visual similarity values from the generated visual similarity values;
• performing a concentration analysis to determine whether the selected top predetermined percentage of highest visual similarity values are concentrated in a diagonal pattern along a temporal alignment corresponding to the matching audio segment;
• and
• determining a match between the first video content item and the second video content item based on the concentration analysis.
