Abstract: Pictures are coded using a coding algorithm with a variable parameter QP so that the quality of the coding varies. First (100), a target value TiMOS is specified for a quality measurement parameter. Then, for each picture (or part of a picture) to be coded, one estimates, independently of the other pictures, a value for the variable parameter QP based on a) the target value for that picture area and b) a masking measure C that depends on the picture content of that picture area. The picture is then coded (112) using the estimated value. The masking measure may be compensated (108, 122) to allow for the effect of the coding quality upon the masking effect.

Abstract: A method and apparatus is provided that converts video content from a first format type into a second format type so that the video content can be viewed with other video content that has the second video format type. The method includes determining a first format of a first stream of video content (702) and determining a second format of a second stream of video content (704, 706). The method also includes converting (806, 808) the format of the second stream of video content into the format of the first stream and combining (812) the first stream of video content with the converted second stream of video content to form. In order to display the first and second video content streams the method decodes the combined first and converted second stream of video content using the first format.

Abstract: An image of the iris contained in an image of an eye is accurately specified. An image of the iris contained in a digital image (P) of an eye is accurately specified. In view of low-intensity pixels of the digital image (P) of the eye, and high-intensity pixels having a predetermined relationship with the low-intensity pixels, a reference pixel (PX0) that defines the center of the pupil is determined. Thereby, the center of the pupil can be specified more accurately when compared to the case where, for example, it is determined only from the low-intensity pixels. Therefore, the accuracy of the process to specify the iris image on the basis of the reference pixel is improved, and as a result, the iris image can be accurately specified.

Abstract: Methods, apparatus, and computer-readable storage media for subspace video stabilization. A subspace video stabilization technique may provide a robust and efficient approach to video stabilization that achieves high-quality camera motion for a wide range of videos. The technique may transform a set of input two-dimensional (2D) motion trajectories so that they are both smooth and resemble visually plausible views of the imaged scene; this may be achieved by enforcing subspace constraints on feature trajectories while smoothing them. The technique may assemble tracked features in the video into a trajectory matrix, factor the trajectory matrix into two low-rank matrices, and perform filtering or curve fitting in a low-dimensional linear space. The technique may employ a moving factorization technique that is both efficient and streamable.

Abstract: Described techniques and tools include techniques and tools for mapping digital media data (e.g., audio, video, still images, and/or text, among others) in a given format to a transport or file container format useful for encoding the data on optical disks such as digital video disks (DVDs). A digital media universal elementary stream can be used to map digital media streams (e.g., an audio stream, video stream or an image) into any arbitrary transport or file container, including optical disk formats, and other transports, such as broadcast streams, wireless transmissions, etc. The information to decode any given frame of the digital media in the stream can be carried in each coded frame. A digital media universal elementary stream includes stream components called chunks. An implementation of a digital media universal elementary stream arranges data for a media stream in frames, the frames having one or more chunks.
