In the context of image retrieval such clouds can be represented in a number of ways. Two approaches are here considered. The first approach is based on the assumption of a normal distribution, hence homogeneous clouds, while the second one focuses on the boundary description, which is more suitable for multimodal clouds. The images are then compared either by using the Mahalanobis distance or by the support vector data description (SVDD), respectively.<\/jats:p><jats:p>The paper investigates some possibilities of combining the image clouds based on the idea that responses of several cloud descriptions may convey a pattern, specific for semantically similar images. A ranking of image dissimilarities is used as a comparison for two image databases targeting image classification and retrieval problems. We show that combining of the SVDD descriptions improves the retrieval performance with respect to ranking, on the contrary to the Mahalanobis case. Surprisingly, it turns out that the ranking of the Mahalanobis distances works well also for inhomogeneous images.<\/jats:p>","DOI":"10.1142\/s0218001404003459","type":"journal-article","created":{"date-parts":[[2004,8,19]],"date-time":"2004-08-19T11:33:59Z","timestamp":1092915239000},"page":"867-890","source":"Crossref","is-referenced-by-count":30,"title":["A STUDY ON COMBINING IMAGE REPRESENTATIONS FOR IMAGE CLASSIFICATION AND RETRIEVAL"],"prefix":"10.1142","volume":"18","author":[{"given":"CARMEN","family":"LAI","sequence":"first","affiliation":[{"name":"Pattern Recognition Group, TU Delft, Lorentzweg 1, Delft, 2628 CJ, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"DAVID M.
