MorphSeek: Fine-grained Latent Representation-Level Policy Optimization for Deformable Image Registration

arXiv CS.CV

ArXi:2511.17392v2 Announce Type: replace Deformable image registration (DIR) remains a fundamental yet challenging problem in medical image analysis, largely due to the prohibitively high-dimensional deformation space of dense displacement fields and the scarcity of voxel-level supervision. Existing reinforcement learning frameworks often project this space into coarse, low-dimensional representations, limiting their ability to capture spatially variant deformations.
