Implicit neural representations for joint decomposition and registration of gene expression images in the marmoset brain

1 code implementation8 Aug 2023 Michal Byra, Charissa Poon, Tomomi Shimogori, Henrik Skibbe

We propose a novel image registration method based on implicit neural representations that addresses the challenging problem of registering a pair of brain images with similar anatomical structures, but where one image contains additional features or artifacts that are not present in the other image.

Improving Segmentation of Objects with Varying Sizes in Biomedical Images using Instance-wise and Center-of-Instance Segmentation Loss Function

1 code implementation13 Apr 2023 Muhammad Febrian Rachmadi, Charissa Poon, Henrik Skibbe

In this paper, we propose a novel two-component loss for biomedical image segmentation tasks called the Instance-wise and Center-of-Instance (ICI) loss, a loss function that addresses the instance imbalance problem commonly encountered when using pixel-wise loss functions such as the Dice loss.

An automated pipeline to create an atlas of in situ hybridization gene expression data in the adult marmoset brain

1 code implementation13 Mar 2023 Charissa Poon, Muhammad Febrian Rachmadi, Michal Byra, Matthias Schlachter, Binbin Xu, Tomomi Shimogori, Henrik Skibbe

We present the first automated pipeline to create an atlas of in situ hybridization gene expression in the adult marmoset brain in the same stereotaxic space.

HAMLET: Hierarchical Harmonic Filters for Learning Tracts from Diffusion MRI

no code implementations3 Jul 2018 Marco Reisert, Volker A. Coenen, Christoph Kaller, Karl Egger, Henrik Skibbe

In this work we propose HAMLET, a novel tract learning algorithm, which, after training, maps raw diffusion weighted MRI directly onto an image which simultaneously indicates tract direction and tract presence.
