1. A method comprising:

  • processing unknown video content to obtain a first fingerprint and a second fingerprint, the first fingerprint being a color-based fingerprint that includes a color-based value determined for each color of a plurality of colors in a portion of the unknown video content, the second fingerprint being a patch-based fingerprint that includes a patch-based value determined for each patch of a plurality of patches in the portion of the unknown video content, wherein each patch-based value is based on at least one of luminance, optical flow, or a Haar-like feature;

    initiating a query of at least one reference database of reference fingerprints using one of the first fingerprint to obtain a candidate group of fingerprints or the second fingerprint to obtain the candidate group of fingerprints, the candidate group of fingerprints being a subset of the reference fingerprints queried; and

    responsive to the query, initiating a query of the candidate group of fingerprints using the other of the first fingerprint and the second fingerprint to identify at least one query fingerprint, wherein the unknown video content is identified using the at least one query fingerprint.
