Wavelet Compression of Multispectral Images

Image compression has been one of the mainstream research topics in image processing. The compression methods are usually developed for images visible to humans , i.e. for gray-scale or RGB images. Recent advances in the eld of remote sensing, however, require us to compress multispectral images. Many methods used in the traditional lossy image compression can be reused also in the compression of multispectral images. In this paper, multidimensional wavelet based transforms are used for the compression. The original three-dimensional image is compressed using one-,two-and three-dimensional wavelets. Furthermore, some quantitative quality measures for multispectral images are presented.
