(Middle) The refractive power of the eye varies with wavelength of light, essentially as if the eye were composed of water. Average axial chromatic aberration of 12 eyes. Data fromBedford and Wyszecki (1957). (Bottom) Chromostereopsis. A target P, not on the optic axis of either eye, em...
The patients' eyes are scanned and sub-surface images are captured from optical nerves. Captured OCT images usually suffer from noise and therefore image enhancement techniques can help doctors in better analysis of OCT images and diagnosis of glaucoma. In this thesis, we propose three successful ...
Glaucoma dataset was labeled into three classes: normal, glaucoma suspect, and glaucoma eyes. Based on the literature we surveyed, this study is the first to classify three status of glaucoma fundus image dataset into three different classes. We compared the evaluation results of TRk-CNN with ...

Dedicated, automatic algorithms for image analysis and processing are becoming more and more common in medical diagnosis. When creating dedicated algorithms, many factors must be taken into consideration. They are associated with selecting the appropriat

glaucoma, retinal pathology, or high myopia) and a history of intraocular surgery or laser treatment were excluded. The Institutional Review Board approval was obtained and the study was conducted in accordance with the declaration of Helsinki. Written informed consent was obtained from all of the ...
The quantile curves method is based on the graphical comparison of a relative representative pallor area size with its determined normal value. The neural net and probability density curves methods can automatically and objectively classify the investigated eyes in exactly defined glaucoma risk classes ...
In an image of the noise, signal features can be discerned. Also, the noise is correlated on a pixel by pixel basis and not uniformly distributed. The general appearance of an image with too few quantization levels may be described as “scalloped.” Fine graduations in intensities are lost...
Standardised slit-image-photographs of the clear human lens in 78 eyes with wide angle glaucoma, 29 eyes with uveitis and 35 eyes after an operation of a retinal detachment were evaluated by microdensitometry and compared with clear lens... P Niesel,E. Bachmann - 《Albrecht Von Graefe S Arc...
