Abstract
To solve the algorithm in the image compression of remote sensing than complex, efficiency lower etc. problem, this paper has put forward a kind of fast, efficient image compressed algorithm on the foundation of little wave coding. Firstly, have gone on for the aspects such as the image compressed coding method, kind and performance appraisement of remote sensing have been further elaborated. Then the coding based on wavelet transform has been described in detail. Finally crucial technology for the image compressed algorithm of remote sensing has carried out thorough research. Experiment result shows: The PSNR value of the image compressed algorithm of remote sensing that this paper adopts has got great advance than traditional algorithm.
Highlights
The algorithm that applies to the image compressed coding of remote sensing includes mainly: Foresee coding and dispersed cosine coding (DCT) as well as dispersed wavelet transform coding (DWT), their neutral can superior coding technology will apply still in the following image compressed coding system of remote sensing
Research applies to the compressed algorithm of the image of remote sensing to have important theoretical meaning and project application value
According to the characteristic of the image compression of remote sensing and requirement, this paper have put forward a kind of fast and efficiently compressed algorithm that applies to the image of remote sensing on foundation of wavelet transform
Summary
The algorithm that applies to the image compressed coding of remote sensing includes mainly: Foresee coding and dispersed cosine coding (DCT) as well as dispersed wavelet transform coding (DWT), their neutral can superior coding technology will apply still in the following image compressed coding system of remote sensing Along with the increase of the image data of remote sensing, the requirement for the image compressed algorithm of remote sensing is high Research applies to the compressed algorithm of the image of remote sensing to have important theoretical meaning and project application value According to the characteristic of the image compression of remote sensing and requirement, this paper have put forward a kind of fast and efficiently compressed algorithm that applies to the image of remote sensing on foundation of wavelet transform
