Publication number: 20240107110Abstract: A method for transitioning from a first set of video tracks, VT1, to a second set of video tracks, VT2, when rendering a multi-track video, wherein each video track has a corresponding rendering priority. The method comprises receiving an instruction to transition from a first set of first video tracks VT1 to a second set of second video tracks VT2, obtaining the video tracks VT2 and, if the video tracks VT2 are different to the video tracks VT1, applying a lowering function to the rendering priority of one or more of the video tracks in the first set of video tracks VT1 and/or an increase function to the rendering priority of one or more video tracks in the second set of video tracks VT2. The lowering function and the increase function decrease and increase the rendering priority over time respectively. The rendering priority is used in the determination of the weighting of a video track and/or elements of a video track used to render a multi-track video.Type: ApplicationFiled: December 3, 2021Publication date: March 28, 2024Inventors: Bart Kroon, Bartolomeus Wilhelmus Damianus Van Geest

Publication number: 20240080431Abstract: An image synthesis apparatus comprises a first receiver (201) receiving three dimensional image data describing at least part of a three dimensional scene and second receiver (203) receiving a view pose for a viewer. An image region circuit (207) determines at least a first image region in the three dimensional image data and a depth circuit (209) determines a depth indication for the first image region from depth data of the three dimensional image data. A region circuit (211) determines a first region for the first image region. A view synthesis circuit (205) generates a view image from the three dimensional image data where the view image representing a view of the three dimensional scene from the view pose. The view synthesis circuit (205) is arranged to adapt a transparency for the first image region in the view image in response to the depth indication and a distance between the view pose and the first region.Type: ApplicationFiled: January 13, 2022Publication date: March 7, 2024Inventors: Bartolomeus Wilhelmus Damianus Van Geest, Bart Kroon

Patent number: 11856223Abstract: A method of generating an image signal from a plurality of images of a scene performs iterations that comprise generating (505) predicted images for a candidate set of images from a set of (previously) included images. A set of selected images is selected (509) from the set of candidate images in response to a prediction quality. For each selected image a subset of pixels is determined (511) in response to pixel prediction qualities for the pixels of the image, and a set of partial images corresponding to the selected images is generated (513) by selecting (511) a subset of pixels. The selected image is deleted from the candidate set and the partial image is added to the included set. The approach may provide a low complexity and low resource selection of image data representing a scene.Type: GrantFiled: February 12, 2020Date of Patent: December 26, 2023Assignee: Koninklijke Philips N.V.Inventors: Bart Kroon, Bartolomeus Wilhelmus Damianus Van Geest

Publication number: 20230370635Abstract: Concepts for encoding and decoding multi-view data for immersive video are disclosed. In an encoding method, metadata is generated comprising a field indicating if a patch data unit of the multi-view data comprises in-painted data for representing missing data. The generated metadata provides a means of distinguishing patch data units comprising original texture and depth data from patch data units comprising in-painted data (e.g. in-painted texture and depth data). The provision of such information within the metadata of immersive video may address problems associated with blending and pruned view reconstruction. Also provided are an encoder and a decoder for multi-view data for immersive video, and a corresponding bitstream, comprising metadata.Type: ApplicationFiled: September 23, 2021Publication date: November 16, 2023Inventors: Bartolomeus Wilhelmus Damianus Van Geest, Bart Kroon, Christiaan Verekamp

Patent number: 7825948Abstract: A 3D video conferencing station includes a video camera for capturing video signals and a depth map calculator for creating a depth map of a user of the 3D video conferencing station. The video signals together with the depth map are transmitted as 3D video data. A stereoscopic display device displays stereo images, which are calculated on the basis of received 3D video data. The depth map which is generated by the depth map calculator is also used for estimating the position of the user in order to control the calculation of the stereo images.Type: GrantFiled: August 9, 2002Date of Patent: November 2, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Bartolomeus Wilhelmus Damianus Van Geest, Marc Joseph Rita Op de Beeck

Patent number: 7692640Abstract: A display apparatus (100) for displaying an output image on basis of 3D visual information is disclosed. The display apparatus (100) comprises: first receiving means (101) for receiving a first signal (3DV) representing the 3D visual information; second receiving means (116) for receiving a second signal (P) representing positional information of a viewer of the output image, as function of time; filtering means (122) for high-pass filtering the second signal (P), resulting in a third signal (PF); rendering means (118) for rendering the output image on basis of the first signal (3DV) and the third signal (PF); and display means (112) for displaying the output image.Type: GrantFiled: September 22, 2004Date of Patent: April 6, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Bartolomeus Wilhelmus Damianus Van Geest, Marc Joseph Rita Op De Beeck

Patent number: 7525565Abstract: A 3D video conferencing station (200, 300, 500, 700) comprises: a camera (104) for acquiring a first (604) and second (602) image of a first user (110); and optical means for visualizing stereo images of a second user, the optical means comprising glasses for the first user (110). The station (200, 300, 500, 700) is arranged to acquire the first image (604) at a first moment at which the left eye of the first user (110) is better observable by the camera (104) than a second moment and to acquire the second image (602) at the second moment at which the right eye of the first user (110) is better observable by the camera (104) than at the first moment. The station further comprises combining means (714) for combining a first portion of the first image (604) and a second portion of the second image (602) into a third image (606) in which the left eye and the right eye of the first user (110) are relatively well visible.Type: GrantFiled: March 11, 2004Date of Patent: April 28, 2009Assignee: Koninklijke Philips Electronics N.V.Inventor: Bartolomeus Wilhelmus Damianus Van Geest
