Lakemond, Ruan, McKinnon, David N., Fookes, Clinton B., & Sridharan, Sridha (2007) A Feature Clustering Algorithm for Scale-space Analysis of Image Structures. In International Conference on Signal Processing and Communication Systems 2007, 17-19 December 2007, Gold Coast, Australia. (In Press)
In describing image features it is important to consider the fact that the appearance of a feature depends on the scale or resolution at which it is observed. Existing robust image feature detectors address the issue by selecting a characteristic scale for each detected feature and subsequently describing the feature as it appears at its characteristic scale. A new method is presented for the multi-scale analysis of derivative based image features that represents a 2D image feature by its locus in scale-space. An algorithm is also presented for efficiently producing the discrete loci representations of image features through clustering features detected at multiple scales. This new method provides an entry point to potential multi-scale descriptions of image features, as well as new possibilities for feature set reduction and filtering.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
