Diffusion based smoothing in medical scans
WebApr 13, 2024 · The short-term bus passenger flow prediction of each bus line in a transit network is the basis of real-time cross-line bus dispatching, which ensures the efficient utilization of bus vehicle resources. As bus passengers transfer between different lines, to increase the accuracy of prediction, we integrate graph features into the recurrent neural … WebTherefore, our aim was to develop a method for volume segmentation and smoothing which achieves interactive performance on standard PCs and is useful in clinical practice (i.e. fast and of high quality). Methods: Our application is based on seeded region growing and nonlinear isotropic as well as anisotropic diffusion. We use current GPUs ...
