Abstract:
1. A computer program product in a recordable-type computer readable medium for classifying media data comprising: first instructions for classifying input media data for later access based on classification in response to receiving the input media data; second instructions for applying a plurality of classifiers in a hierarchical classification structure to the input media data; third instructions for generating confidence scores for the plurality of classifiers in the hierarchical classification structure; fourth instructions for modifying a confidence score automatically for a classifier in the hierarchical classification structure based on a relationship between the classifier and other classifiers in the hierarchical classification structure and the confidence scores of the other classifiers in the hierarchical classification structure, wherein the fourth instructions for modifying the confidence score automatically for a classifier include instructions for applying a confusion factor to the confidence score based on a correspondence between the confidence score and confidence scores of mutually exclusive classifiers in the hierarchical classification structure, and wherein the confusion factor is determined as a function of a difference between the confidence score of the classifier and a maximum confidence score from mutually exclusive classifiers in the hierarchical classification structure; fifth instructions for generating a representation of the input media data based on the modified confidence score being higher than a predetermined threshold confidence score; and sixth instruction for storing the generated representation of the input media data.
