Impact of PCA-based preprocessing and different CNN structures on deformable registration of sonograms

no code implementations20 Jan 2023 Christian Schmidt, Heinrich Martin Overhoff

The impact of principal component analysis (PCA)-based pre-denoising of patient individual images, as well as the impact of modified net structures with differing complexities on registration results were examined visually and quantitatively, the latter using metrics for deformation and image similarity.

D^2Conv3D: Dynamic Dilated Convolutions for Object Segmentation in Videos

1 code implementation15 Nov 2021 Christian Schmidt, Ali Athar, Sabarinath Mahadevan, Bastian Leibe

We further show that D^2Conv3D out-performs trivial extensions of existing dilated and deformable convolutions to 3D.

MDEmic in a use case for microscopy metadata harmonization: Facilitating FAIR principles in practical application with metadata annotation tools

1 code implementation4 Mar 2021 Susanne Kunis, Sebastian Hänsch, Christian Schmidt, Frances Wong, Caterina Strambio-De-Castillia, Stefanie Weidtkamp-Peters

Similar to public image data repositories like the Image Data Resource, IDR, this database facilitates image data storage including rich metadata which enables data mining and re-use, one of the major goals of the FAIR principles.

Simulating Yang-Mills theories with a complex coupling

no code implementations11 Jan 2021 Jan M. Pawlowski, Manuel Scherzer, Christian Schmidt, Felix P. G. Ziegler, Felix Ziesché

We discuss the structure of Generalized Lefschetz thimbles for pure Yang-Mills theories with a complex gauge coupling $\beta$ and show how to incorporate the gauge orbits.

Dense Limit of the Dawid-Skene Model for Crowdsourcing and Regions of Sub-optimality of Message Passing Algorithms

no code implementations13 Mar 2018 Christian Schmidt, Lenka Zdeborová

We further study numerically the performance of approximate message passing, derived in the dense limit, on sparse instances and carry out experiments on a real world dataset.
