- Abstract summary: We demonstrate a method to obtain organ labels in real time by using a large context size with a sparse data sampling strategy.
Although our method operates as an independent classifier at query locations, it can generate full segmentations by querying grid locations at any resolution.

- Abstract: Organ segmentation is a fundamental task in medical imaging since it is useful for many clinical automation pipelines. However, some tasks do not require full segmentation. Instead, a classifier can identify the selected organ without segmenting the entire volume. In this study, we demonstrate a classifier based method to obtain organ labels in real time by using a large context size with a sparse data sampling strategy. Although our method operates as an independent classifier at query locations, it can generate full segmentations by querying grid locations at any resolution, offering faster performance than segmentation algorithms. We compared our method with existing segmentation techniques, demonstrating its superior runtime potential for practical applications in medical imaging.

Semantic Segmentation and Localization [98.46318529630109]
We take inspiration from traditional spectral segmentation methods by reframing image decomposition as a graph partitioning problem.
We find that these eigenvectors already decompose an image into meaningful segments, and can be readily used to localize objects in a scene.
By clustering the features associated with these segments across a dataset, we can obtain well-delineated, nameable regions.
