WebEdge-preserving smoothing or edge-preserving filtering is an image processing technique that smooths away noise or textures while retaining sharp edges. Examples are the median, bilateral, guided, anisotropic diffusion, and Kuwahara filters. Introduction [ edit] WebSep 15, 2024 · Temporal volume images with 3D+t (4D) information are often used in medical imaging to statistically analyze temporal dynamics or capture disease progression. Although deep-learning-based generative models for natural images have been extensively studied, approaches for temporal medical image generation such as 4D cardiac volume …

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 … WebMar 28, 2024 · In this paper, we propose a novel SISR diffusion probabilistic model (SRDiff) to tackle the over-smoothing, mode collapse and large footprint problems in previous SISR models. Specifically, 1) to extract the image information from an LR image, SRDiff exploits a pre-trained LR encoder to convert the LR image into hidden conditions; …
WebDiffusion magnetic resonance imaging (dMRI) is an in vivo and noninvasive medical imaging technology that uses water diffusion as a proxy to probe anatomical structures of biological samples. The most important applica- tion of dMRI is to reconstruct white matter fiber tracts in the brain—large axonal bundles with similar destinations.
