The work reviews despeckling as a key preprocessing step and contrasts spatial-domain and transform-domain filtering approaches, including local statistical, bilateral, Bayesian risk-based, anisotropic diffusion, and wavelet-based methods such as DWT, UDWT, and DTCWT, along with their trade-offs in edge preservation, ringing, shift variance, and computational complexity.","cbCaiiTrBJqM5jRf","https://ap.wps.com/l/cbCaiiTrBJqM5jRf","pdf",4568199,1,11,"English","en","",1776565392,28,{"code":4,"msg":27,"data":28},"ok",{"site_id":29,"language":22,"slug":30,"title":13,"keywords":23,"description":14,"schema_data":31,"social_meta":66,"head_meta":68,"extra_data":70,"updated_unix":24},105,"speckle-noise-removal-in-sar-images-using-multi-objective-pso-mopso",{"@graph":32,"@context":65},[33,50],{"@type":34,"itemListElement":35},"BreadcrumbList",[36,40,44,47],{"item":37,"name":38,"@type":39,"position":19},"https://docshare.wps.com","Home","ListItem",{"item":41,"name":42,"@type":39,"position":43},"https://docshare.wps.com/document/","Document",2,{"item":45,"name":12,"@type":39,"position":46},"https://docshare.wps.com/document/research-report/",3,{"item":48,"name":13,"@type":39,"position":49},"https://docshare.wps.com/document/speckle-noise-removal-in-sar-images-using-multi-objective-pso-mopso/16275",4,{"url":48,"name":13,"@type":51,"author":52,"headline":13,"publisher":54,"fileFormat":57,"description":14,"dateModified":58,"datePublished":59,"encodingFormat":57,"isAccessibleForFree":60,"interactionStatistic":61},"DigitalDocument",{"name":9,"@type":53},"Person",{"url":37,"name":55,"@type":56},"DocShare","Organization","application/pdf","2026-05-11","2026-04-19",true,{"@type":62,"interactionType":63,"userInteractionCount":19},"InteractionCounter",{"@type":64},"ViewAction","https://schema.org",{"og:url":48,"og:type":67,"og:title":13,"og:site_name":55,"og:description":14},"article",{"robots":69,"canonical":48},"index,follow",{"doc_id":7,"site_id":29}]
