@article{(Open Science Index):https://publications.waset.org/pdf/4760, title = {New Wavelet-Based Superresolution Algorithm for Speckle Reduction in SAR Images}, author = {Mario Mastriani}, country = {}, institution = {}, abstract = {This paper describes a novel projection algorithm, the Projection Onto Span Algorithm (POSA) for wavelet-based superresolution and removing speckle (in wavelet domain) of unknown variance from Synthetic Aperture Radar (SAR) images. Although the POSA is good as a new superresolution algorithm for image enhancement, image metrology and biometric identification, here one will use it like a tool of despeckling, being the first time that an algorithm of super-resolution is used for despeckling of SAR images. Specifically, the speckled SAR image is decomposed into wavelet subbands; POSA is applied to the high subbands, and reconstruct a SAR image from the modified detail coefficients. Experimental results demonstrate that the new method compares favorably to several other despeckling methods on test SAR images. }, journal = {International Journal of Computer and Information Engineering}, volume = {2}, number = {3}, year = {2008}, pages = {935 - 942}, ee = {https://publications.waset.org/pdf/4760}, url = {https://publications.waset.org/vol/15}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 15, 2008}, }
