Remote Sensing Image Pyramid Model Based on Wavelet Multi-resolution Analysis

With the rapid development of remote sensing technology and application requirements, the volumes of remote sensing image data become more and more large, which brings management of massive image a big test. An improved construction method of remote sensing image pyramid based on wavelet multi-resolution analysis has been researched. Using the multi-resolution analysis and the theory of wavelet decomposition and reconstruction algorithm, on the base of the general way to construct an image pyramid, wavelet decomposition coefficient from different levels are quantified and coded, then stored in different layers of the image pyramid. It is great significance in effective management for vast amounts of remote sensing image. It can reduce the total amounts of data and the data traffic while browsing, and a better progressive transmission effect has been realized.
