| 摘要 |
The present invention relates to a method, apparatus and computer program product for providing contour information related to images. An image obtaining unit obtains a set of interrelated images (step 26), an image segmenting unit segments said images, (step 28) and a contour determining unit (22) extracts at least two contours from the segmentation (step 30), selects interest points on the contours of each image (step 32), associates interest points with corresponding reconstructed points by means of three-dimensional reconstruction (step 34), projects reconstructed points into the images (step 36), and links reconstructed points not projected at a junction or their projections to each other in order to provide a first set of links (step 38), such that at least a reasonable part of a contour of an object can be determined based on the linked reconstructed points.
