Abstract:

In this paper, the classical managing and indexing methods of image data are presented, the deficiencies of the method are also analyzed, To solve the problems in the classical method, a new managing and indexing method based on non-uniform partitioning is proposed in this paper. It avoids the massive   time and space cost caused by zero-padding on the edges of images. The result of experiments shows that the proposed method can support region query an d seamless mosaic among distributed images efficiently. The time and soace cost is much less than that of the classical ones.

Key words: image data index, zero-padding, partition, grid index, pyramid index
