Editing of presegemented images/volumes with the multilabel random walker or graph cut segmentations
First Claim
Patent Images
1. A method for processing an object in a set of image data comprising presegmenting the object using a first segmentation process;
- analyzing the presegmentation of the object and determining a weighting factor based on the analysis of the presegmentation;
placing one or more seeds in the set of image data; and
segmenting the object using a second segmentation process using the seeds and the weighting factor and the results from the first segmentation process.

Abstract
Presegmentation or prior, pre-existing segmentation of an object obtained through other means will be presented for interactive editing of a segmented object in an image or volume. Prior segmentation will be seamlessly combined with graph cuts or the random walker methods. Editing of the presegmentation is possible, while maintaining the important property of both methods that an arbitrary segmentation may be achieved with enough interaction.
