Abstract

The disclosure notably relates to a computer-implemented method for generating a template image of an organ. The method comprises obtaining a dataset comprising a set of medical images, and an autoencoder pre-trained on a set of medical images. The method comprises determining the template image, by minimizing in the latent space a loss which is a function of the latent vector and, for each medical image of the dataset, parameters of a diffeomorphic deformation applied to the template image to obtain the medical image. The loss includes a first term penalizing a discrepancy between a posterior probability of the parameters of the diffeomorphic deformation, given the medical image, and a Gaussian prior probability of the parameters of the diffeomorphic deformation. The loss includes a second term penalizing a negative log-likelihood of the set of medical images of the dataset, given the latent vector and the parameters of the diffeomorphic deformation.
