Problems solved by technology

[0008] However, these methods are heuristic based and can link parts of the scene for which there is no visual evidence of connectivity
There are also many cases where large and complex calculations are required, as this can make it difficult to tell if an object occludes another object, i.e. where there are junctions between object outlines in multiple images

Embodiment Construction

[0058] The invention will now be described in light of the enclosed drawings, first referring to Figure 1A -C, multiple images are displayed, Figure 5shows a schematic block diagram of a device according to the invention, and Image 6 A flow diagram of the method according to the invention is shown. Figure 5 The device 16 in includes a camera 18 that captures interrelated images in a plurality of frames. In order to better explain the present invention, in Figure 1A -C shows only three static scenes captured by the camera from three different angles for one frameI 1 , I 2 and I 3 . The camera thus acquires images by capturing them, step 26 , and then forwards them to the image segmentation unit 20 . The image segmentation unit 20 segments the image in the frame, step 28 . Segmentation is performed in this exemplary embodiment by analyzing the color of the image, where regions with the same color are identified as segments. The segmented image is then forwarded to th...

Abstract

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.

Description

technical field [0001] The present invention generally relates to the field of simplified encoding of objects in images, and more particularly to a method, apparatus and computer program product for providing contour information related to images. [0002] thank you [0003] Philips thanks the Universidad do Minho in Portugal for their cooperation in making the filing of this patent application possible. Background technique [0004] In the field of computer-generated images and video, a great deal of work has been done on generating three-dimensional models from two-dimensional images to further enhance the visibility of scenes. An area of ​​interest in this sort of thing is the area of ​​3D TV projection. All of this is possible if there is sufficient information in the two-dimensional image that can be used to determine the distance to the object from the point where the image was captured. [0005] So far there are different approaches, such as measuring the apparent ...
