Abstract

An algorithm for measuring an index of leakage in fluorescein fundus angiography is presented. The number of pixels whose gray level exceeds an automatically determined slice level is calculated. An automatic blood vessel elimination technique is introduced. Further, a method of measuring the short term change of leakage from a time series of the fluorescein fundus angiographs is described. Our system can also deal with the time series images obtained on different occasions (long term change).

The features of this paper are: (1) this paper deals with double time sequence images (short and long term); (2) an automatic blood vessel recognition algorithm is employed.

Detection of blood vessels in ophthalmoscope images using MF/ant (matched filter/ant colony) algorithm
2009, Computer Methods and Programs in Biomedicine
Blood vessels in ophthalmoscope images play an important role in diagnosis of some serious pathologies on retinal images. Hence, accurate extraction of vessels is becoming a main topic of this research area. Matched filter (MF) implementation for blood vessel detection is one of the methods giving more accurate results. Using this filter alone might not recover all the vessels (especially the capillaries). In this paper, a novel approach (MF/ant algorithm) is proposed to overcome the deficiency of the MF. The proposed method is a hybrid model of matched filter and ant colony algorithm. In this work, the accuracy and parameters of the hybrid algorithm are also discussed. The proposed method shows its success using the well known reference ophthalmoscope images of DRIVE database.

Zero-crossing interval correction in tracing eye-fundus blood vessels
1988, Pattern Recognition
We are developing a health screening system for color eye-fundus photography. The system is designed to detect the first signs of adult diseases, for which purpose it is important to detect and trace eye blood vessels. This paper describes a method of finding the papilla by Hough transform, and from there tracing blood vessels by a second-order derivative Gaussian filter. The width of the blood vessel is obtained as the zero-crossing interval of the filter output. The filter is adjustable to the current width of the blood vessel being traced. In this process, since the obtained zero-crossing interval is larger than the true width of an ideal step-wise blood vessel, it is corrected at each step.
