COMBINING RESULTS OF IMAGE RETRIEVAL PROCESSES
First Claim
1. An method for combining recognition results, the method comprising:
- receiving a first recognition result and a first confidence score associated with the first recognition result;
receiving a second recognition result and a second confidence score associated with the second recognition result;
computing a first recognizability score corresponding to the first recognition result;
computing a second recognizability score corresponding to the second recognition result;
determining a recognition output using the first confidence score, the second confidence score, the first recognizability score and the second recognizability score.

Abstract
A MMR system for newspaper publishing comprises a plurality of mobile devices, an MMR gateway, an MMR matching unit and an MMR publisher. The MMR matching unit receives an image query from the MMR gateway and sends it to one or more of the recognition units to identify a result including a document, the page and the location on the page. The MMR matching unit also includes a result combiner coupled to each of the recognition units to receive recognition results. The result combiner produces a list of most likely results and associated confidence scores. This list of results is sent by the result combiner back to the MMR gateway for presentation on the mobile device. The result combiner uses the quality predictor as an input in deciding which results are best. The present invention also includes a number of novel methods including a method for generating the list of best results.

15. An method for combining recognition results using predicted values, the method comprising:
-
computing a first recognizability score corresponding to a first recognition algorithm; computing a second recognizability score corresponding to a second recognition algorithm; determining whether the first recognizability score is above a threshold; determining whether the second recognizability score is above a threshold; and if the first recognizability score and the second recognizability score are both above a threshold performing recognition on an input image to generate a first recognition result and a first confidence score, performing recognition on the input image to generate a second recognition result and a second confidence score; and determining a recognition output using the first confidence score, the second confidence score. - View Dependent Claims (16, 17, 18, 20)
