摘要：
The invention relates to a method implemented by computer means for characterizing at least one organ of a patient in at least one medical image, said method comprising the following iterative steps of:
segmenting (6) said organ in at least one image (7) representing a healthy organ, so as to obtain at least one segmentation mask (8) of said healthy organ,
generating additional segmentation masks of said healthy organ, using at least one data augmentation method (9) on the basis of the segmentation mask obtained in step (a), said data augmentation method (9) being a shape-preserving method,
training an autoencoder (10) with the segmentation mask obtained in step (a) and the additional segmentation masks obtained in step (b) to encode the shape of said organ in a latent space (11).
