A simple approach to the detection and extraction of blood vessels in retinal images using MATLAB software. There are 60 retinal image samples from the STARE and DRIVE database. The implementation process begins with the change from a retinal colour image to a grayscale image followed by improvement techniques. These enhancement techniques involve opening by rebuilding and transforming top hat to improve the performance of conventional methods of extracting blood vessels. The process of morphology that is realized by the opening by reconstruction and the technique of transformation of upper hat are significant for the following process of extraction. The morphology process is followed by the local entropy threshold and filtration process. The extraction process of the proposed method took less than 1 minute to extract the blood vessels with an average precision and sensitivity of 0.89 and 0.71.
Support Vector Machine (SVM) is a non-linear classifier that is often reported to produce superior classification results in comparison to other methods. The idea behind the method is to align the input data in a non-linear way with a high dimensional space, where the data can be separated linearly, thus providing a high classification (or regression) performance. One of the bottlenecks of the SVM is the large number of support vectors used from the training set to perform classification (regression) tasks. In my code, I use SSE optimization to increase performance.
