Particularly, registering satellite images is challenging and time-consuming due to limited resources and large image size. In such scenario, state-of-the-art image registration methods such as scale-invariant feature transform (SIFT) may not be suitable due to high processing time. In this paper, we propose an algorithm based on block processing via entropy to register satellite images. The performance of the proposed method is evaluated using different real images. The comparative analysis shows that it not only reduces the processing time but also enhances the accuracy.<\/jats:p>","DOI":"10.3390\/e14122397","type":"journal-article","created":{"date-parts":[[2012,11,27]],"date-time":"2012-11-27T11:14:30Z","timestamp":1354014870000},"page":"2397-2407","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Entropy-Based Block Processing for Satellite Image Registration"],"prefix":"10.3390","volume":"14","author":[{"given":"Ikhyun","family":"Lee","sequence":"first","affiliation":[{"name":"School of Information and Mechatronics, Gwangju Institute of Science and Technology (GIST), 123 Cheomdan gwagiro, Buk-Gu, Gwangju 500-712, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Doo-Chun","family":"Seo","sequence":"additional","affiliation":[{"name":"Satellite Data Cal\/Val Team, Korea Aerospace Research Institute, 45 Eundong Yusunggu, Daejon 305-333, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tae-Sun","family":"Choi","sequence":"additional","affiliation":[{"name":"School of Information and Mechatronics, Gwangju Institute of Science and Technology (GIST), 123 Cheomdan gwagiro, Buk-Gu, Gwangju 500-712, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2012,11,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1615","DOI":"10.1109\/TPAMI.2005.188","article-title":"A performance evaluation of local descriptors","volume":"27","author":"Mikolajczyk","year":"2005","journal-title":"IEEE Trans.
