  • Method and device for segmenting images by automatic propagation into an (N+1 )-th dimension of an image segmentation initialized in dimension N
    Patent number: 11004220
    Abstract: This method (100) for automatic propagation into an (N+1)-th dimension of an image segmentation initialized in dimension N, N?2, comprises the acquisition (102) of an ordered series of image representations of dimension N and an initial segmentation (104) in dimension N of a region of interest in the first and last image representations of the series, to obtain first and last initial segmentation masks (M0, Mn) of the region of interest. It further comprises an estimation (106) of registration parameters (La, Ld) between the first and last initial segmentation masks, and upward and downward automatic propagations (108) of the initial segmentation, from the first and last image representations, to all the other image representations of the series by step-by-step registration up to the last and first image representations.
