摘要： The invention relates to a method of generating a synthesized image representing a view of a scene from a first input image representing the view and a second input image representing the view, the synthesized image comprising synthesized image positions, by assigning a synthesized image data value to a synthesized image position. The method comprises determining whether input images have at the synthesised image position data values associated with them. If either one has a data value associated, that data value is assigned to the synthesized image position. If both, an average of both values is assigned. The average is a weighed average, with weighing factors being a function of a distance or distances to a closest image position with no image data value or valid image data value assigned.

摘要： An objective video quality estimation technique is disclosed. The technique may be based on a video bitstream model, using parameters taken from the video coding layer of the bitstream for estimating the quality of the video. The technique can be implemented as a method, a computer program, a computer program product, a device, or any one of a server node, a client terminal and a network node comprising the device. As a method embodiment, the technique comprises receiving a video bitstream comprising a series of picture frames; determining an error occurrence in a picture frame of the video bitstream; determining at least one of a temporal propagation and a spatial propagation of the error; and estimating the quality of the video bitstream based on result of the determination.

摘要： Systems and techniques for efficient free-space finger recognition are herein described. A surface in a depth image may be identified. One or more blobs in the depth image may be identified. The identified blobs may be analyzed to determine if a blob intersects with an edge of the depth image and classified as a potential hand if the blob does intersect with the edge or classified as an object otherwise.

摘要： Viewer interaction herein triggers switching from a first view point to a second view point and thereby controls presentation of video sequences. Each video sequence comprises a sequence of images of one and the same subject and is associated with a respective view point. Images are obtained from a first video sequence associated with a first view point and are provided for presentation. Viewer input information is received that indicates a desire to present a second view point. In response, a start position within a second video sequence associated with the second view point is determined, and the obtaining of images from the first video sequence is discontinued as of the determined start position. Images are then obtained from the second video sequence associated with the second view point, starting from the determined start position, and are then provided for presentation.

摘要： In a method of distributing media content with overlay graphical information from a media server to a media client the graphical information is extracted from the media content and transmitted to a media client. Prior to encoding the media content, each frame that comprises an area of graphical information is processed in separate blocks, in a manner such that an introduction of visual artefacts in the vicinity of the graphical information is avoided. The encoded media content is then transmitted to the media client, where the media content will be reproduced by adding the graphical information as an overlay on top of the decoded media content, but without comprising any coding originated artefacts.

摘要： A communication device and method provide selective control of a level of buffering of at least one data stream. The communication device includes a jitter buffer (202), a jitter buffer control unit (204) and a user interface (206). An instruction received via an input to a user interface (206) indicates a jitter buffer strategy (510), such as enabling a jitter buffer or setting a size of a jitter buffer, based on the user input. The control unit (204) sets the buffer strategy based in the instruction, and a data stream transmitted via a packet-switched network is received (530) and buffered for play out based on the buffer strategy (540).

摘要： Identifying lost data packets and at least two intra coded frames of a video stream can be useful in determining the quality value of the video stream. The intra coded frames having maintained image quality can be determined based on estimating whether an intra coded frame is associated with a lost data packet. This allows a distance to be estimated between each one of the lost data packets and a next respective, subsequent intra coded frame having a maintained image quanta. Based on the distances, a quality value for the video stream can be generated.
