چکیده
* Research supported by NASA Contract NAS5-00213. Abstract Moderate Resolution Imaging Spectroradiometer (MODIS) data are collected from the Terra satellite at a rate of 11 megabits/second. These data are to be transmitted to earth, stored, and analyzed by various algorithms. One solution to reducing the bandwidth and storage need for these data is to apply wavelet-based compression, which is known to provide good performance. We present a controlled study that shows the effect of data compression on cloud cover classification of MODIS data. We find that cloudcover calculations can tolerate very large compression ratios. The correlation between frequency bands can be used to compress MODIS images even further.

The drought can be described as a natural disaster in each region. In this study, one of the important factors in drought, vegetation, has been considered. For this purpose, monthly vegetation cover images and snow cover data of MODIS and TRMM satellite precipitation product from 2009 to 2018 were used for the study area of Iran. After initial preprocessing, we have used artificial neural netwo...
متن کاملSatellite Image Compression Technique Using Noise Bit Removal and Discrete Wavelet Transform
A feature of satellite images is the presence of noise, where this noise often requires preprocessing of the images by a denoising method adapted prior to their compression, storage and transmission. In this work to improve the compression scheme, we are interested in image compression by discarding noisy bits from the satellite image and discrete wavelet transform (DWT). This method was tested...

متن کاملParallel compact coding of satellite images with wavelet packets using PVM
Image compression methods that use wavelet transforms have been successful in providing high rates of compression while maintaining good image quality. Even superior to these wavelet techniques are methods based on wavelet packet decompositions. When processing satellite data the amount of data suggests to use a parallel approach. Wavelet packet decomposition with best basis selection is implem...
