Patent ID: 8682074

Claim:
A method for checking a segmentation of a structure in image data, the segmentation to be checked providing a segmentation region that approximates the structure imaged in the image data and is delimited by a segmentation contour, the method comprising: automatically determining spatially resolved characteristic values serving as an indicator of an accuracy of the segmentation of the structure on the basis of the image data; and automatically determining spatially resolved confidence values for a plurality of positions on the segmentation contour using the automatically determined characteristic values determined for corresponding positions, wherein the spatially resolved characteristic values include gradients of intensity values in the image data, in which the structure is imaged, gradients of probability values of a probability map determined using a random walker segmentation method during a segmentation of the structure in the image data in the course of the method for checking, or curvature values of probability isocontour lines in the probability map.
