Active Contour Models are the essential instruments for image segmentation and have great development in both theory and application. However, these existing models cannot work well in the presence of intensity heterogeneity, and are in general sensitive to initial curve places. Therefore, a novel active contour is proposed so as to extract correctly vessels, which takes into account image intensity and vessel features simultaneously. The new model is obtained by local phase vesselness-enhanced algorithm, and is based on local binary fitting. Experimental results, which based on publicly available Digital Retinal Images for Vessel Extraction (DRIVE), show that our model can successfully extract the desired vessels in the presence of intensity inhomogeneity with 74.43% pixel sensitivity and 93.67% segmentation accuracy, and the model is insensitive to initial curve placement. This demonstrates our model is competent for image segmentation with high accuracy and robustness.
