Abstract
One embodiment of the present invention sets forth a technique for training a machine learning model to perform semantic segmentation. The technique includes iteratively extracting, from a set of 3D images, a first set of three-dimensional (3D) patches having a first patch size and a second set of 3D patches having a second patch size, where the second patch size is smaller than the first patch size. The technique also includes training the machine learning model using the first set of 3D patches and a first set of losses associated with the first set of 3D patches. The technique further includes training the machine learning model using the second set of 3D patches and a second set of losses associated with the second set of 3D patches.
