A new formulation of active contours based on explicit functions has been recently suggested. This novel framework allows real-time 3-D segmentation since it reduces the dimensionality of the segmentation problem. In this paper, we propose a B-spline formulation of this approach, which further improves the computational efficiency of the algorithm. We also show that this framework allows evolving...
Automatic quantification of regional left ventricular function in volumetric ultrasound data remains challenging. Our lab previously presented such an approach based on elastic registration of subsequent volumes using a b-spline representation of the underlying transformation field. Good results were obtained for the assessment of global function, but a thorough validation on a regional level was...
