Intraocular lens power calculation and optimized constants for highly myopic eyes.

30 Aug 2009 PURPOSE: To determine the accuracy of intraocular lens (IOL) power calculations in eyes with high myopia and to suggest adjusted constants for these cases. SETTING: Centre for Ophthalmology, Eberhard-Karls-University, Tuebingen, Germany. METHODS: ... Read more...

Toward accurate and fast iris segmentation for iris biometrics.

30 Aug 2009 Iris segmentation is an essential module in iris recognition because it defines the effective image region used for subsequent processing such as feature extraction. Traditional iris segmentation methods often involve an exhaustive search of a large ... Read more...

The development of the cervical vertebrae as an indicator of skeletal maturity: comparison with the classic method of hand-wrist radiograph.

31 Jul 2009 OBJECTIVE: The objective of this study was to compare three methods with which to determine the skeletal maturity of children. MATERIALS AND METHODS: The methods were Greulich & Pyle's atlas method based on hand-wrist radiographs (1959), and the ... Read more...
