Retinal Blood Vessel Detection Using Multiscale Line Filter and Phase Congruency
نویسندگان
چکیده
In this paper, a multiscale line filter is proposed which is integrated with phase congruency to detect the network of vessels in retinal images. The proposed line filter can reduces the influence of step edges compared with Gaussian matched filter, and the post process use the phase congruency demonstrated a substantial improvement in detecting vessels which have low contrast or minor width. The performance of the proposed method is evaluated on the publicly available databases DRIVE and STARE. The experimental results show that an effective and robust detection can be achieved.

متن کاملExtracting Vessel Centerlines From Retinal Images Using Topographical Properties and Directional Filters
In this paper we consider the problem of blood vessel segmentation in retinal images. After enhancing the retinal image we use green channel of images for segmentation as it provides better discrimination between vessels and background. We consider the negative of retinal green channel image as a topographical surface and extract ridge points on this surface. The points with this property are l...
متن کاملRetinal Vessel Centerline Extraction Using Multiscale Matched Filter and Sparse Representation-Based Classifier
Retina located in the back of the eye contains useful information in the diagnosis of certain diseases. By locating a blood vessel’s width, color, reflectivity, tortuosity and abnormal branching, one can deduce the existence of these diseases. In order for this to be achieved, blood vessels first need to be extracted from its background in fundus image. In this paper we propose a new method to ...
