Abstract :
In this paper we investigate the performance of H.264 intra coding for synthetic aperture radar (SAR) image. The results show that H.264 intra coding is a high performance coder for the SAR image. However, when the SAR image is despeckled, H.264 Intra coding is not so efficient than the wavelet based image coder, such as JPEG2000 and SPIHT. Then more efficient representation is needed when H.264 Intra Coding is used to code the despeckled SAR image.
