Methods and Devices for Image Segmentation by Automatic Propagation of Image Segmentation Initialized to Dimension N to Dimension (N + 1) Dimension

摘要

This method for automatically propagating image segmentation initialized to dimension N, where N ≧ 2, is described in step (102) of obtaining an ordered series of image representations of dimension N. , The first and final image representations of the series include step (104) of performing initial segmentation in dimension N of the region of interest to obtain first and final initial segmentation masks (M ₀ , Mn) of the region of interest. Method, between the first and last of the initial segmentation mask, registration parameters (L _{a, Ld)} and step (106) for estimating a first and last image representation, the step-by-step registration, series For all other image representations, further includes step (108) of autopropagating above and below the initial segmentation up to the final and first image representations. Upper and lower automatic propagation, then the estimated registration parameters _{(L a,} L _d) obtained by applying, combined together using between the first and last image registration, the reference frame changes (110, 112).
