Reconstruction of glymphatic transport fields from subject-specific imaging data, with particular emphasis on cerebrospinal fluid flow and tracer conservation

·10 min read·A. Derya Bakiler, Michael J. Johnson, Michael R. A. Abdelmalik et al.

This paper tackles a very specific inverse-problem pain point in image-based transport modeling: if you try to reconstruct flow and clearance fields directly from noisy spatiotemporal imaging, the …

Continuous-tone Simple Points: An $ll_0$-Norm of Cyclic Gradient for Topology-Preserving Data-Driven Image Segmentation

·12 min read·Wenxiao Li, Faqiang Wang, Yuping Duan et al.

This paper addresses a specific gap in topology-aware image segmentation: classical simple-point topology is defined on binary images and is non-differentiable, which makes it awkward to use with m…
