It is an extension of the inverted beta distribution, an important texture model for SAR imagery. The considered distribution extension approach increases the flexibility of the baseline distribution, and is a new probabilistic model useful in SAR image applications. Besides introducing the new model, the maximum likelihood method is discussed for parameter estimation. Numerical experiments are performed to validate the use of the ET-IB distribution as a SAR amplitude image descriptor. Finally, three measured SAR images referring to forest, ocean, and urban regions are considered, and the performance of the proposed distribution is compared to distributions usually considered in this field. The proposed distribution outperforms the competitor models for modeling SAR images in terms of some selected goodness-of-fit measures. The results show that the ET-IB distribution is suitable as a SAR descriptor and can be used to develop image-processing tools in remote sensing applications.<\/jats:p>","DOI":"10.3390\/rs14122853","type":"journal-article","created":{"date-parts":[[2022,6,15]],"date-time":"2022-06-15T01:39:54Z","timestamp":1655257194000},"page":"2853","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["A New Probability Distribution for SAR Image Modeling"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2976-3891","authenticated-orcid":false,"given":"Murilo","family":"Sagrillo","sequence":"first","affiliation":[{"name":"Programa de P\u00f3s-Gradua\u00e7\u00e3o em Engenharia de Produ\u00e7\u00e3o, Universidade Federal de Santa Maria, Santa Maria 97105-900, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6476-8276","authenticated-orcid":false,"given":"Renata R.","family":"Guerra","sequence":"additional","affiliation":[{"name":"Departamento de Estat\u00edstica, Universidade Federal de Santa Maria, Santa Maria 97105-900, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1464-0805","authenticated-orcid":false,"given":"F\u00e1bio M.","family":"Bayer","sequence":"additional","affiliation":[{"name":"Departamento de Estat\u00edstica and LACESM, Universidade Federal de Santa Maria, Santa Maria 97105-900, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0856-5391","authenticated-orcid":false,"given":"Renato","family":"Machado","sequence":"additional","affiliation":[{"name":"Department of Telecommunications, Aeronautics Institute of Technology (ITA), S\u00e3o Jos\u00e9 dos Campos 12228-900, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"775","DOI":"10.3390\/s100100775","article-title":"Statistical modeling of SAR images: A survey","volume":"10","author":"Gao","year":"2010","journal-title":"Sensors"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"4190","DOI":"10.1109\/TGRS.2012.2227754","article-title":"Multiphase SAR image segmentation with G0-statistical-model-based active contours","volume":"51","author":"Feng","year":"2013","journal-title":"IEEE Trans.
