Abstract:
1. A computer-implemented process for characterizing a first representation or view of a semantic object in the form of a first binary hash code representing that semantic object such that when compared to a characterized version of a second representation or view of the same semantic object in the form of a second binary hash code representing that semantic object, the first and second binary hash codes exhibit a degree of similarity indicative of the objects being the same object, said process comprising: using a computer to perform the following process actions: inputting pairs of parallel semantic objects, wherein a pair of parallel semantic objects comprises the same semantic object presented in the first and second representations or views; subjecting each semantic object in each pair of parallel semantic objects to feature extraction to produce a feature vector representing the semantic object; establishing a prescribed number of transforms for the first representation or view and the same number of transforms for the second representation or view based on the feature vectors representing the parallel semantic object pairs, wherein the transforms established for one of the first or second representations or views, when applied to a feature vector representing a semantic object exhibiting that representation or view, produces the first binary hash code representing that semantic object which is substantially similar to the second binary hash code representing that semantic object produced when the transforms established for the other of the first or second representations or views are applied to a feature vector representing the same semantic object exhibiting that other representation or view, and wherein said transforms established for the first representation or view are not all the same as the transforms established for the second representation or view; and using the transforms established for the first representation or view to characterize a semantic object exhibiting the first representation or view as the first binary hash code representing that semantic object.
