Synthetic Aperture Radar (SAR) is an important tool for obtaining information from the surface of the Earth with the capability of producing high resolution images. SAR has the advantage of all-weather sensing and it has tremendous applications in areas such as the military, agriculture, oceanography, resource mapping, and so on. However, SAR image is contaminated by speckle which is multiplicative...
Most distributed source coding (DSC) compression methods for hyperspectral image in transform domain are based on discrete wavelet transform (DWT). However, we point out that DWT domain is not efficient for the on-board acquisition system, which requires simple encoder. We find hyperspectral image is also highly correlated in discrete cosine transform (DCT) domain, and the computational cost of DCT...
