Evaluation of Various Aggregation Operators Applied to a Content Based Image Retrieval System

چکیده
Fuzzy Hamming Distance is successfully used in a Content-Based Image Retrieval (CBIR) system as a similarity measure. The system performs a m × n partitioning of the compared images and for each partitions pairs evaluates FHD. In the last step the FHD are defuzzified and the results are combined in a final score. In order to take full advantage of the use of fuzzy sets, the current study investigates the possibility of reversing the order of the defuzzification and aggregation steps: aggregate fuzzy set and defuzzify final result for ranking. Several t-norm and associated t-conorm aggregation operators are experimented with. The results are illustrated on retrieval operations from an image database.
