摘要:In most practical applications of image retrieval, high-dimensional feature vectors are required, butcurrent multi-dimensional indexing structures lose their efficiency with growth of dimensions. Our goal isto propose a divisive hierarchical clustering-based multi-dimensional indexing structure which is efficientin high-dimensional feature spaces. A projection pursuit method has been used for finding a component ofthe data, which data's projections onto it maximizes the approximation of negentropy for preparingessential information in order to partitioning of the data space. Various tests and experimental results onhigh-dimensional datasets indicate the performance of proposed method in comparison with others.
