Very low rate compression of speckled SAR imagery
Paul H. Eichel, Robert W. Ives · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1998
Synthetic aperture radars produce coherent, and speckled, high resolution images of the ground. Because modern systems can generate large amounts of imagery, there is substantial interest in applying image compression techniques to these products. In this paper, the authors examine the properties of speckled imagery relevant to the task of data compression. In particular, they demonstrate the advisability of compressing the speckle mean function rather than the literal image. The theory, methodology, and an example are presented.
