Generally, FSS assumes that base classes and novel classes belong to the same domain, which limits FSS\u2019s application in a wide range of areas. In particular, since annotation is time-consuming, it is not cost-effective to process remote sensing images using FSS. To address this issue, we designed a feature transformation network (FTNet) for learning to few-shot segment remote sensing images from irrelevant data (FSS-RSI). The main idea is to train networks on irrelevant, already labeled data but inference on remote sensing images. In other words, the training and testing data neither belong to the same domain nor category. The FTNet contains two main modules: a feature transformation module (FTM) and a hierarchical transformer module (HTM). Among them, the FTM transforms features into a domain-agnostic high-level anchor, and the HTM hierarchically enhances matching between support and query features. Moreover, to promote the development of FSS-RSI, we established a new benchmark, which other researchers may use. Our experiments demonstrate that our model outperforms the cutting-edge few-shot semantic segmentation method by 25.39% and 21.31% in the one-shot and five-shot settings, respectively.<\/jats:p>","DOI":"10.3390\/rs15204937","type":"journal-article","created":{"date-parts":[[2023,10,12]],"date-time":"2023-10-12T12:46:13Z","timestamp":1697114773000},"page":"4937","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Learn to Few-Shot Segment Remote Sensing Images from Irrelevant Data"],"prefix":"10.3390","volume":"15","author":[{"given":"Qingwei","family":"Sun","sequence":"first","affiliation":[{"name":"Department of Aerospace Science and Technology, Space Engineering University, Beijing 101416, China"},{"name":"China Astronaut Research and Training Center, Beijing 100094, China"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-2276-7856","authenticated-orcid":false,"given":"Jiangang","family":"Chao","sequence":"additional","affiliation":[{"name":"China Astronaut Research and Training Center, Beijing 100094, China"},{"name":"National Key Laboratory of Human Factors Engineering, China Astronaut Research and Training Center, Beijing 100094, China"}]},{"given":"Wanhong","family":"Lin","sequence":"additional","affiliation":[{"name":"China Astronaut Research and Training Center, Beijing 100094, China"},{"name":"National Key Laboratory of Human Factors Engineering, China Astronaut Research and Training Center, Beijing 100094, China"}]},{"given":"Zhenying","family":"Xu","sequence":"additional","affiliation":[{"name":"China Astronaut Research and Training Center, Beijing 100094, China"},{"name":"National Key Laboratory of Human Factors Engineering, China Astronaut Research and Training Center, Beijing 100094, China"}]},{"given":"Wei","family":"Chen","sequence":"additional","affiliation":[{"name":"China Astronaut Research and Training Center, Beijing 100094, China"},{"name":"National Key Laboratory of Human Factors Engineering, China Astronaut Research and Training Center, Beijing 100094, China"}]},{"given":"Ning","family":"He","sequence":"additional","affiliation":[{"name":"China Astronaut Research and Training Center, Beijing 100094, China"},{"name":"National Key Laboratory of Human Factors Engineering, China Astronaut Research and Training Center, Beijing 100094, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Wang, Z., Wang, B., Zhang, C., Liu, Y., and Guo, J.
