A New Efficient Ellipse Detection Method

In this paper, we introduce a new method for ellipse detection. This method takes the advantages of major axis of an ellipse to find ellipse parameter fast and efficiently. It only needs an one-dimensional accumulator array to accumulate the length information for minor axis of the ellipse. This method does not require the evaluation of the tangents or curvatures of the edge contours, which are...

A Statistically Efficient Method for Ellipse Detection

In this paper, we introduce a statistically efficient method f o r detecting ellipses in a n image. Given a set of digital arc segments, we introduce geometric criteria t o select possible pairs of arc segments belonging to the same ellipse. T h e selected arc pairs are subsequently validated or rejected based o n certain statistical criteria via hypothesis testing. The advantages of our techni...

The Effect of Cataract on Early Stage Glaucoma Detection Using Spatial and Temporal Contrast Sensitivity Tests

BACKGROUND To investigate the effect of cataract on the ability of spatial and temporal contrast sensitivity tests used to detect early glaucoma. METHODS Twenty-seven glaucoma subjects with early cataract (mean age 60 ± 10.2 years) which constituted the test group were recruited together with twenty-seven controls (cataract only) matched for age and cataract type from a primary eye care setti...

Early detection of glaucoma.

Primary open-angle glaucoma (often loosely called "chronic glaucoma") is one of the main causes of preventable loss of sight in Britain1 2 and throughout the world. All too often it is diagnosed only when loss ofthe visual fields is advanced and the condition is resistant to treatment.3 Early detection is therefore of the highest importance, especially with recent evidence that appreciable neur...

sperm detection in video frames of semen sample using morphology and effective ellipse detection method

casa (computer assisted semen analysis) systems are designed to assist andrologist labour. most available casa systems are not accurate or so expensive. therefore labours use manual methods to provide parameters. although some companies have achieved appropriate accuracy, they have not released their methods. so proposing methods in this area might be useful for groups who intend to design new ...
