Web position tracking

A system for facilitating web position tracking, the system comprising at least one processor configured to:

• receive a representation of a plurality of first-stage anomaly locations representing locations of anomalies detected on a web at a first web processing stage;
• receive a representation of a plurality of second-stage anomaly locations representing locations of anomalies detected on the web at a second web processing stage;
• for each of a plurality of different candidate location offsets:
• compare the candidate location offset to the plurality of first-stage anomaly locations and the plurality of second-stage anomaly locations to determine a representation of a difference to be associated with the candidate location offset;
• and
• associate the representation of the difference with the candidate location offset;
• and
• identify a determined location offset from the candidate location offsets based at least in part on the representations of the differences.

A non-transitory computer-readable medium having stored thereon codes that when executed by at least one processor cause the at least one processor to:

• receive a representation of a plurality of first-stage anomaly locations representing locations of anomalies detected on a web at a first web processing stage;
• receive a representation of a plurality of second-stage anomaly locations representing locations of anomalies detected on the web at a second web processing stage;
• for each of a plurality of different candidate location offsets:
• compare the candidate location offset to the plurality of first-stage anomaly locations and the plurality of second-stage anomaly locations to determine a representation of a difference to be associated with the candidate location offset;
• and
• associate the representation of the difference with the candidate location offset;
• and
• identify a determined location offset from the candidate location offsets based at least in part on the representations of the differences.

A system for facilitating web position tracking, the system comprising:

• means for receiving a representation of a plurality of first-stage anomaly locations representing locations of anomalies detected on a web at a first web processing stage;
• means for receiving a representation of a plurality of second-stage anomaly locations representing locations of anomalies detected on the web at a second web processing stage;
• means for, for each of a plurality of different candidate location offsets:
• comparing the candidate location offset to the plurality of first-stage anomaly locations and the plurality of second-stage anomaly locations to determine a representation of a difference to be associated with the candidate location offset;
• and
• associating the representation of the difference with the candidate location offset;
• and
• means for identifying a determined location offset from the candidate location offsets based at least in part on the representations of the differences.
