Abstract
Methods and apparatus for identifying media content using temporal signal characteristics are disclosed. An example apparatus includes at least one memory, computer readable instructions, and at least one processor to execute the instructions to identify intervals in a media signal; generate interval sums for respective ones of the intervals, a first interval sum of the interval sums based on a sum of magnitudes of first peaks of the media signal that occur between zero crossings of a first interval of the intervals of the media signal; identify second peaks based on the interval sums; and generate a signature representative of the media signal based on the second peaks.

A computing system
- comprising:
- at least one processor;
- and
- memory having stored therein machine-readable instructions that, when executed by the at least one processor, cause the computing system to perform a set of operations comprising:
- defining interval sums for respective intervals of audio information associated with a media signal based on first peaks in the audio information associated with the media signal;
- identifying second peaks based on the interval sums;
- generating normalized curve features to have a same height and a same width at respective temporal locations, the normalized curve features represented as triangular-shaped peaks, wherein each apex of the triangular-shaped peaks is at each of the respective temporal locations corresponding to the second peaks;
- and
- generating a media signature including the normalized curve features, the media signature to compare with one or more reference signatures to identify the media signal.
A method comprising:
- defining interval sums for respective intervals of audio information associated with a media signal based on first peaks in the audio information associated with the media signal;
- identifying second peaks based on the interval sums;
- generating normalized curve features to have a same height and a same width at respective temporal locations, the normalized curve features represented as triangular-shaped peaks, wherein each apex of the triangular-shaped peaks is at each of the respective temporal locations corresponding to the second peaks;
- and
- generating a media signature including the normalized curve features, the media signature to compare with one or more reference signatures to identify the media signal.
A non-transitory computer-readable medium having stored therein instructions that, when executed by at least one processor, cause performance of:
- defining interval sums for respective intervals of audio information associated with a media signal based on first peaks in the audio information associated with the media signal;
- identifying second peaks based on the interval sums;
- generating normalized curve features to have a same height and a same width at respective temporal locations, the normalized curve features represented as triangular-shaped peaks, wherein each apex of the triangular-shaped peaks is at each of the respective temporal locations corresponding to the second peaks;
- generating a media signature including the normalized curve features, the media signature to compare with one or more reference signatures to identify the media signal.
