Combining results of image retrieval processes

A method for combining recognition results using predicted values, the method comprising:

• computing, with a processor, a first recognizability score corresponding to a first recognition algorithm using at least an input image and contextual information including one or more from a group of a date, a time, a location of a device that transmitted the input image, a personal profile and a retrieval history;
• computing, with the processor, a second recognizability score corresponding to a second recognition algorithm using the input image and contextual information including one or more from a group of the date, the time, the location of the device that transmitted the input image, the personal profile and the retrieval history;
• determining whether the first recognizability score is above a threshold;
• determining whether the second recognizability score is above a threshold;
• and
• when the first recognizability score and the second recognizability score are both above a threshold:
• performing recognition on the input image to generate a first recognition result, a first confidence score, and first document information associated with the first recognition result;
• performing recognition on the input image to generate a second recognition result, a second confidence score, and second document information associated with the second recognition result;
• modifying the first confidence score and the second confidence score using the first recognizability score and the second recognizability score, respectively;
• determining votes for each of the first recognition result based in part on the first modified confidence score and the first document information, and the second recognition result based in part on the second modified confidence score and the second document information;
• and
• determining a recognition output by selecting one of the first recognition result and the second recognition result with a highest number of votes.
