Fitting Segmentation Networks on Varying Image Resolutions using Splatting. (arXiv:2206.06445v2 [eess.IV] UPDATED)

Data used in image segmentation are not always defined on the same grid. This
is particularly true for medical images, where the resolution, field-of-view
and orientation can differ across channels and subjects. Images and labels are
therefore commonly resampled onto the same grid, as a pre-processing step.
However, the resampling operation introduces partial volume effects and
blurring, thereby changing the effective resolution and reducing the contrast
between structures. In this paper we propose a splat layer, which automatically
handles resolution …
