Fuzzy snakes
No full textA new method for representing and tracking of object boundaries is presented, which allows for the integration of uncertain a priori knowledge into an active contour model. The new fuzzy snake allows for an intuitive specification of the properties of an object's boundary. This is obtained by setting up a linguistic rule base, which describes each of the fuzzy snake's segments. Furthermore the approximate length of each contour segment may be specified to improve the segmentation process and to reduce the computational complexity
Fuzzy active contour model
No full textA new method for representing and tracking of object boundaries is presented, which allows for the integration of uncertain a priori knowledge into an active contour model. The novel concept of fuzzy snakes is developed to allow for an intuitive specification of the properties of an object's boundary. This is achieved by introducing fuzzy energy functions and establishing a linguistic rule base, which describes each of the fuzzy snake's segments. Furthermore the approximate length of each contour segment may be specified to both improve the segmentation process and to reduce computational complexity. Experimental results demonstrate the validity of the theoretical properties of the fuzzy snake approach, and examples have been included illustrating the application of the technique to complex scenes, such as medical imaging sequences
