Abstract: As we all know, the region scalable fitting method is sensitive to initialisations and suffers from bad results in images with complex scene. In our article, we put forward a new framework by integrating region scalable fitting (RSF) term and difference of Gaussian (DOG) term for segmenting images. We first propose a DOG function which can enhance the contrast at the edges of objects. Then, the RSF energy term is introduced to drive the curve closer to the edge. In the next step, the regularisation term is established which can avoid of the process of reinitialisation. Compared with traditional classical methods, the proposed technique is more flexibility with initialisation and has better segmentation performance.
Keywords: difference of Gaussian; DOG; region scalable fitting; RSF; active contour; image segmentation.
