Learning a Generative Motion Model from Image Sequences based on a Latent Motion Matrix
IEEE Transactions on Medical Imaging(2021)
摘要
We propose to learn a probabilistic motion model from a sequence of images for spatio-temporal registration. Our model encodes motion in a low-dimensional probabilistic space – the motion matrix – which enables various motion analysis tasks such as simulation and interpolation of realistic motion patterns allowing for faster data acquisition and data augmentation. More precisely, the motion matrix...
