摘要： The invention relates to a method and apparatus of determining depth information of an image by use of T -junctions. An apparatus comprises a segmentation processor (201) which receives an image and segments it into a plurality of image segments having similar characteristics. The segments are fed to a junction extraction processor (203) which determines T -junction candidates. The image segments and T -junction candidates are fed to a depth information processor (205) which determines depth information associated with objects of the image in response to the T-junction candidates. Specifically, predetermined junction models are fitted to the T junction candidates and the model having the closest fit is selected. Depth information for the T -junction is then determined from known depth information of the junction model. In addition certainty measures are determined for the T-junction candidates and the associated depth information.

摘要： The invention relates to a system for determining depth information for a video image. The video image is segmented (703) to determine a plurality of image segments. A plurality of junction points associated with the plurality of image segments are determined (705). The junction points may be between three different objects, between two different objects or within a single object. For each junction point, independent depth information data is determined (707, 709, 711) assuming that the junction point corresponds to each of the three possible object associations. The reliability of the assumption is determined in response to a fit of a corresponding model and a depth characteristic is derived (713) by selecting the most reliable information. The depth characteristics of a multiplicity of junction points are then used to determine a depth map. By determining and using depth information of all junction points and not just object T-junctions, additional and improved depth information is obtained.

摘要： A method of converting of a first set (100a) of initial segments of an image into a second set of updated segments (A',B',C',D') is disclosed. The method comprises iterative updates of intermediate segments (A,B,C,D) being derived from respective initial segments. Each update comprises determining whether a pixel (300) should be moved from a first intermediate segment (A) to a second intermediate segment (B), on basis of a pixel value of the pixel, on basis of a first parameter of the intermediate segment (A) and on basis of a second parameter of the second intermediate segment (B). The iterative updates are performed on block base. That means that first a number of iterative updates are performed for pixels of a first two-dimensional block of pixels (200) of the image and after that the number of iterative updates are performed for pixels of a second two-dimensional block of pixels (204) of the image.

摘要： In a method for relative depth of parts of one or more digital images, the digital images are regularized by segmentation, and at least part of the pixels of the images are assigned to respective segments. The realtive motion of the segments for successive images is estimated by image matching. The image features of the segments are regularized by dual segmetation, in which the edges of the segments are found, pixels are assigned to the edges, and dual segments are defined. The relative motion of the dual segments for successive images is estimated by image segment matching in order to determine the relative depth order of the image segments.

摘要： In a method for encoding and an encoder for a 3D video signal, centre view frames, a depth map for centre view frames and an occlusion data frame are encoded. On the basis of the depth map for the centre view frame a distinction is made between functional and non- functional data in an occlusion data frame. This allows a strong reduction in bits needed for the encoded occlusion data frame. In the decoder a combined data stream is made of functional data in the encoded occlusion data frames and the centre view frames. Preferably the centre view frames are used as reference frames in encoding the occlusion data frames.
