Available in PDF, EPUB and Kindle. Book excerpt: Retinal image formation through the optics of the human eye is the first step in the complex process of vision. Imperfections in the optics of the human eye, including aberrations and scatter, degrade retinal image quality. Determination of the contribution of ocular aberrations and light scatter to decreased retinal image quality, particularly in aging and diseased eyes, is essential to evaluate optical quality of the eye. Correction of ocular aberrations can enable acquiring retinal images with high spatial resolution. An optical imaging system has been established that provides for combined measurements of ocular aberrations and light scatter. Wavefront sensing was performed with a Shack-Hartmann aberrometer to determine the wavefront aberration function and calculate the point spread function, giving information on ocular aberrations. A line spread function was derived from the laser slit, giving information on combined ocular aberrations and light scatter. A relative index for ocular light scatter was derived. A hybrid deconvolution method for improving retinal image quality was developed.

Download or read book Quantitative Analysis and Modeling of Confocal Retinal Images written by Jiyun Byun and published by ProQuest. This book was released on 2007 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Images have become critical components for a detailed understanding of the structure and function of cells and proteins. For example, confocal microscopy images are used to obtain a better understanding of several critical functions of the central nervous system (CNS), such as mechanisms behind the loss and recovery of vision following retinal detachment. Image processing and information discovery tools increasingly play a significant role in better harvesting these vast amounts of data, most of which is currently analyzed manually and qualitatively.

Download or read book Automated Delineation and Quantitative Analysis of Blood Vessels in Retinal Fundus Image written by Xiayu Xu and published by . This book was released on 2012 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Automated fundus image analysis plays an important role in the computer aided diagnosis of ophthalmologic disorders. A lot of eye disorders, as well as cardiovascular disorders, are known to be related with retinal vasculature changes. Many studies has been done to explore these relationships. However, most of the studies are based on limited data obtained using manual or semi-automated methods due to the lack of automated techniques in the measurement and analysis of retinal vasculature. In this thesis, a fully automated retinal vessel width measurement technique is proposed. This novel method models the accurate vessel boundary delineation problem in two-dimension into an optimal surface segmentation problem in threedimension. Then the optimal surface segmentation problem is transformed into finding a minimum-cost closed set problem in a vertex-weighted geometric graph. The problem is modeled differently for straight vessel and for branch point because of the different conditions in straight vessel and in branch point. Furthermore, many of the retinal image analysis needs the location of the optic disc and fovea as a prerequisite information, for example, in the analysis of the relationship between vessel width and the distance to the optic disc. Hence, a simultaneous optic disc and fovea detection method is presented, which includes a two-step classification of three classes. The major contributions of this thesis include: 1) developing a fully automated vessel width measurement technique for retinal blood vessels, 2) developing a simultaneous optic disc and fovea detection method, 3) validating the methods using multiple datasets, and 4) applying the proposed methods in multiple retinal vasculature analysis studies.

Download or read book A Computer aided System for Interactive Image Analysis of Retinal Pathologies Using Optical Coherence Tomography written by Sudarshan Ranganathan and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this thesis is to design a new stand-alone application software consisting of a Graphical User Interface (GUI) that will integrate a novel automatic segmentation of the retinal images obtained from the StratusOCT(TM) system along with a new developed manual correction tool that will aid in eliminating segmentation errors. Additionally, the GUI will integrate a set of programmed functions to facilitate the pre- and post-processing of the StratusOCT(TM) images. It will also generate a quantitative analysis report that can be exported as a spreadsheet to Microsoft Excel along with a PDF document. As a result, the GUI will facilitate the measurements of thickness and reflectance of the various retinal layers, leading to a potential improvement in the quantitative analysis of StratusOCT(TM) images.
