Extracting centerlines of coronary arteries is a challenging but important task in clinical applications of cardiac computed tomography angiography (CTA). In this paper, we propose an inertia-driven path tracking method based on the directional minimal path (DMP) to automatically extract the coronary centerlines. In DMP, the path tracing is divided into a number of segments. The proposed method adopts...
In the process of the sonar image analysis, the information of the shadow and echo are very significant. However, most of the segmentation methods are failed to abstract the useful information from the background with strong noises. To overcome this problem, we apply the Markov random field to segment the features of sonar images, which expresses the spatial correlation of the image pixels sufficiently...
As the exploration of the seabed is extended ever further, automated recognition and classification of sonar images become increasingly important. However, most of the related methods ignore the directional information and scale invariance or only pay attention to one of them. To deal with this problem, we combine 2D Gabor filters and fuzzy fractal dimension based on the information fusion method...
