METHOD AND APPARATUS FOR COMPRESSION OF SAR IMAGES

摘要

A computer system 60 for compressing synthetic aperture radar (SAR) image s includes a database for storing SAR images to be compressed, and a process or 69 for compressing a SAR image from the database. The compressing include s applying an anisotropic diffusion algorithm to the SAR image, and compress ing the SAR image after applying the anisotropic diffusion algorithm thereto . Applying the anisotropic diffusion algorithm includes determining noise in the SAR, selecting a noise threshold for the SAR image based on the determi ned noise, and mathematically adjusting the anisotropic diffusion algorithm based on the selected noise threshold.
