UNSUPERVISED MULTITASK ENSEMBLE FOR SPATIAL TRANSFER OF MULTI-STRUCTURES VIA PARTIAL POINT CLOUD MATCHING

Systems and methods for registering a plurality of medical images are provided. A plurality of partial point clouds of anatomical objects is received. Each of the plurality of partial point clouds is extracted from a respective one of a plurality of medical images. A set of missing points is generated for each of the plurality of partial point clouds. A measure of certainty is generated for each point in 1) the plurality of partial point clouds and 2) the sets of missing points. One or more transformations aligning the plurality of partial point clouds is determined based on the measures of certainty using a machine learning based point registration network for registering the plurality of medical images. The one or more transformations are output.
