PURPOSE To report a novel method for measuring the vertical tilt angle of the optic nerve (ON) head and to investigate the associated factors. DESIGN Cross-sectional diagnostic study. METHODS One hundred and twelve normal, glaucomatous, and glaucoma suspect eyes (99 patients) were enrolled in this study. Subjects underwent a full eye examination, biometry, and spectral-domain optical cohere...

This paper presents a quantitative analysis of the error of the edge angle measurement obtained from edge detector in the presence of grey level gaussian noise. Our analysis shows that the uncertainty of the angle measurement is only related to the grey level noise power and the gradient of the edge point at which the angle is measured. Both image independent upper bound and image dependent est...
