    Abstract: Described is picture segmentation through columns and slices in video encoding and decoding. A video picture is divided into a plurality of columns, each column covering only a part of the video picture in a horizontal dimension. All coded tree blocks (“CTBs”) belonging to a slice may belong to one or more columns. The columns may be used to break the same or different prediction or in-loop filtering mechanisms of the video coding, and the CTB scan order used for encoding and/or decoding may be local to a column. Column widths may be indicated in a parameter set and/or may be adjusted at the slice level. At the decoder, column width may be parsed from the bitstream, and slice decoding may occur in one or more columns.

    Abstract: A method and apparatus for creating and updating a facial image database from a collection of digital images is disclosed. A set of detected faces from a digital image collection is stored in a facial image database, along with data pertaining to them. At least one facial recognition template for each face in the first set is computed, and the images in the set are grouped according to the facial recognition template into similarity groups. Another embodiment is a naming tool for assigning names to a plurality of faces detected in a digital image collection. A facial image database stores data pertaining to facial images detected in images of a digital image collection. In addition, the naming tool may include a graphical user interface, a face detection module that detects faces in images of the digital image collection and stores data pertaining to the detected faces in the facial image database, a face recognition module that computes at least one facial recognition template for each facial image in the facial image database, and a similarity grouping module that groups facial images in the facial image database according to the respective templates such that similar facial images belong to one similarity group.

    Abstract: A system and method for adjusting a video bit rate (VBR) over a network includes reducing the VBR if the network incurs a packet loss (PL) that is greater than a PL threshold increasing the VBR if the PL is less than or equal to the PL threshold over a maximum integer number of time intervals and increasing the maximum integer number of time intervals if the PL is greater than the packet loss threshold at the increased VBR. In addition, the VBR is increased over consecutive time intervals until a maximum video bit rate is restored, if the PL over each consecutive time interval is less than or equal to the packet loss threshold.

    Abstract: Methods and systems for estimating the amount of visible light in a light source using an image sensor, e.g., such as an image sensor of the type commonly found in color video cameras. The methods and systems may be implemented to use information about the normalized differences of three color components contained in a light source in conjunction with a measure of total light energy of the light source in order to estimate the amount of visible light present in light received by the image sensor from a light source.

    Abstract: The present invention allows higher quality video images to be transmitted without a concomitant increase in a total number of video data bits transmitted per frame. Quantization parameters are applied to coefficients of macroblocks within a given video frame. A lower value of the quantization parameter is applied near a central region of a video frame. This central region is referred to as a prime video region. Applying the lower quantization parameter to the prime video region has the effect of increasing the video data bit density within that area. Outside of the prime video region, the video data bit density per macroblock is decreased so as to have a zero net-gain in bit density over the entire video frame. Furthermore, there may be a plurality of prime video regions where quantization parameters are dynamically coded. In this case, the value of the quantization parameter will increase or decrease within a given prime video region based on a relative importance of a particular prime video region. Consequently, a quantization parameter matrix may vary depending on the video scene.

    Abstract translation: 本发明允许传输更高质量的视频图像，而不伴随每帧传输的视频数据比特数的总和增加。 量化参数被应用于给定视频帧内的宏块的系数。 在视频帧的中心区域附近施加较低的量化参数值。 该中心区域被称为主要视频区域。 将较低量化参数应用于主视频区域具有增加该区域内的视频数据位密度的效果。 在主视频区域之外，每个宏块的视频数据比特密度减小，从而在整个视频帧上具有零比特密度的净增益。 此外，可以存在多个主要视频区域，其中量化参数被动态地编码。 在这种情况下，基于特定主要视频区域的相对重要性，量化参数的值将在给定的主视频区域内增加或减少。 因此，量化参数矩阵可以根据视频场景而变化。

    Abstract: A system for establishing a voice and signaling link through a PBX system from an remote telephone device includes a PBX system, a setless gateway, and an remote telephone device. The PBX system is coupled to a public switched telephone network (PSTN) via a trunk connection. The PBX system is also coupled to the setless gateway via a digital phone port, which includes a first bearer channel B1 and a second bearer channel B2. DTMF tone sequences from the remote telephone device are decoded by the setless gateway, which acts as a proxy to the PBX system. The setless gateway routes voice and signaling from the second bearer channel B2 to the first bearer channel B1, so as to extend the remote telephone device from the PBX system.
