Investigation of Dynamic Reconstruction Methods for Remote Sensing Image Pyramids Based on Multi-resolution Characteristic of Wavelet Transformation

Base on multi-resolution characteristic of wavelet transformation, a dynamic reconstruction method of image pyramids for remote sensing imagery is proposed in this paper. The method can solve the data redundant problems caused by traditional reconstruction methods, for which the correlation characteristic of the data between different pyramid layers is not used. It can effectively reduce the amount of data storage and network data transmission, and form a stream data transferring mode. Therefore, it is fairly appropriate for the network distributing of remote sensing imagery. Systematic experiments were done for this method. And compared with traditional methods, the response efficiency is improved significantly, which verifies the feasibility and superiority of the method in the storage and transmission of remote sensing imagery.
