Efficiency comparative analysis between two search algorithms using DT CWT for content-based image retrieval

摘要

The following paper presents a comparative analysis on the efficiency of two search algorithms for Content-Based Image Retrieval. Both algorithms are designed using the Dual-Tree Complex Wavelet Transform for image feature extraction and Hausdorff distance for similarity distance computation. The difference in the steps of the algorithms produces difference in the final result. To estimate the efficiency of the algorithms, we performed some experiments and compared their results. They clearly show that one of the algorithms provides much higher retrieval rate and system performance than the other.
