It is proven that the transformation from Polar to Cartesian representation contributes to decreased mutual information, and hence to greater distinctiveness. The Complex Scale-Invariant Feature Transform (\u2102SIFT) detects distinctive features in complex-valued images. An evaluation method for estimating the uniformity of feature distributions in complex-valued images derived from intensity-range images is proposed. In order to experimentally evaluate the proposed methodology on intensity-range images, three different kinds of active sensing systems were used: Range Imaging, Laser Scanning, and Structured Light Projection devices (PMD CamCube 2.0, Z+F IMAGER 5003, Microsoft Kinect).<\/jats:p>","DOI":"10.3390\/rs3092076","type":"journal-article","created":{"date-parts":[[2011,9,16]],"date-time":"2011-09-16T10:42:45Z","timestamp":1316169765000},"page":"2076-2088","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Improved Feature Detection in Fused Intensity-Range Images with Complex SIFT (\u2102SIFT)"],"prefix":"10.3390","volume":"3","author":[{"given":"Patrick Erik","family":"Bradley","sequence":"first","affiliation":[{"name":"Institute of Photogrammetry and Remote Sensing, Karlsruhe Institute of Technology, Kaiserstr. 12, D-76128 Karlsruhe, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4322-3074","authenticated-orcid":false,"given":"Boris","family":"Jutzi","sequence":"additional","affiliation":[{"name":"Institute of Photogrammetry and Remote Sensing, Karlsruhe Institute of Technology, Kaiserstr. 12, D-76128 Karlsruhe, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2011,9,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"177","DOI":"10.1561\/0600000017","article-title":"Local invariant feature detectors: A survey","volume":"3","author":"Tuytelaars","year":"2008","journal-title":"Found.
