A Refined Bootstrap Method for Estimating the Zernike Polynomial Model Order for Corneal Surfaces
Iskander, D. Robert, Morelande, Mark R., Collins, Michael J., & Buehren, Tobias F. (2004) A Refined Bootstrap Method for Estimating the Zernike Polynomial Model Order for Corneal Surfaces. IEEE Transactions of Biomedical Engineering, 51(12), pp. 2203-2206.
Abstract—Following our previous work on optimal modeling of corneal surfaces with Zernike polynomials, we have developed a refined bootstrapbased procedure which improves the accuracy of the previous method.We showthat for normal corneas, the optimal number of Zernike terms usually corresponds to the fourth or fifth radial order expansion of Zernike polynomials. On the other hand, for distorted corneas such as those encountered in keratoconus or in surgically altered cases, the estimated model was found to be up to three radial orders higher than for normal corneas.
Impact and interest:
Citation counts are sourced monthly from and 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 downloads displays 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.
