Lossless and lossy compression for MODIS level 0 data

In this paper, we study the lossless and lossy compression methods for MODIS Level 0 data. Firstly, in order to decrease the compression time we use the simple image partitioning algorithm for MODIS image before compression. The experimental results show that by using the partitioning algorithm the compression time can be decreased about 25%. Then we present some lossless and lossy compression methods for MODIS level 0data. For lossless compression the experiments show that using the interband predictor helps to improve the compression rate because the redundancy among bands is reduced. For lossy compression we utilize some wavelet based methods to compress the denoised images. Finally we present the lossless and lossy compression results for MODIS image data by the methods.
