In this paper, we propose a new method for speeding up retrieval of subregions in natural images by using tree structures. We evaluate our method by fractal compression, and moreover we apply the method to image mining. In our method a tree called an index tree is generated from given subregions by using bit planes. Our experiments show that faster fractal compression is achieved by using index trees. As the application of our method to image mining, we treat the problem of extracting frequent subregions as features of an image. As a solution, we propose a new method to nd sets of frequent paths from sets of index trees. We give some experimental results showing that we can regard the number of frequent subregions as features of an image. We also found same images whose waveform cannot be regarded as features. |
