基于小波变换的遥感图像压缩编码方法

摘要

遥感技术在人民生活和社会生产的应用非常广泛. 随之而来的海量遥感数据对信息的传输、 处理和存储都是巨大的挑战, 应对这个问题的重要方法之一就是对图像进行压缩编码处理. 提出一种基于小波变换的压缩编码方法, 利用遥感图像的先验知识来提高算法的压缩性能和效率. 实验结果表明, 新算法性能较传统压缩算法提高约1倍.%Remote sensing technologies are widely used in everyday-life and industry. Massive remote sensing data brings great challenges for transmission,processing and storage. Image compression and encoding is an important method to solve this problem. An encoding method based on wavelet transform is proposed in this paper,which provides improved compression performance and efficiency using prior knowledge of images.Experiments show the performance is improved doubly over traditional algorithm.
