Abstract: This paper studies the multiresolution analysis and classification of the textured synthetic aperture radar (SAR) image using the wavelet transform (WT).The tree-structured WT algorithm is first employed to decompose a real-world textured SAR image,and to quantify different texture types in the image.Then,the pyramid-structured WT algorithm is applied in multiresolution classification of the image.The classification result obtained demonstrates the advantage of the WT in the textured SAR image classification.
