It is applied to remotely sensed imagery for many problems such as land use classification and landscape changes. Recently, several hybrid remote sensing image segmentation techniques have been proposed that include metaheuristic approaches in order to increase the segmentation accuracy; however, the critical point of these approaches is the high computational complexity, which affects time and memory consumption. In order to overcome this criticality, we propose a fuzzy-based image segmentation framework implemented in a GIS-based platform for remotely sensed images; furthermore, the proposed model allows us to evaluate the reliability of the segmentation. The Fast Generalized Fuzzy c-means algorithm is implemented to segment images in order to detect local spatial relations between pixels and the Triple Center Relation validity index is used to find the optimal number of clusters. The framework elaborates the composite index to be analyzed starting by multiband remotely sensed images. For each cluster, a segmented image is obtained in which the pixel value represents, transformed into gray levels, the graph belonging to the cluster. A final thematic map is built in which the pixels are classified based on the assignment to the cluster to which they belong with the highest membership degree. In addition, the reliability of the classification is estimated by associating each class with the average of the membership degrees of the pixels assigned to it. The method was tested in the study area consisting of the south-western districts of the city of Naples (Italy) for the segmentation of composite indices maps determined by multiband remote sensing images. The segmentation results are consistent with the segmentations of the study area by morphological and urban characteristics, carried out by domain experts. The high computational speed of the proposed image segmentation method allows it to be applied to massive high-resolution remote sensing images.<\/jats:p>","DOI":"10.3390\/s23249641","type":"journal-article","created":{"date-parts":[[2023,12,5]],"date-time":"2023-12-05T11:27:06Z","timestamp":1701775626000},"page":"9641","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A Novel Fuzzy-Based Remote Sensing Image Segmentation Method"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9844-9513","authenticated-orcid":false,"given":"Barbara","family":"Cardone","sequence":"first","affiliation":[{"name":"Department of Architecture, University of Naples Federico II, Via Toledo 402, 80134 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5690-5384","authenticated-orcid":false,"given":"Ferdinando","family":"Di Martino","sequence":"additional","affiliation":[{"name":"Department of Architecture, University of Naples Federico II, Via Toledo 402, 80134 Naples, Italy"},{"name":"Center for Interdepartmental Research \u201cAlberto Calza Bini\u201d, University of Naples Federico II, Via Toledo 402, 80134 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vittorio","family":"Miraglia","sequence":"additional","affiliation":[{"name":"Department of Architecture, University of Naples Federico II, Via Toledo 402, 80134 Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Qiao, H., Wan, X., Wan, Y., Li, S., and Zhang, W.
