    • 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.

    • Disclosed herein are techniques and computer readable media containing instructions arranged to utilize existing video compression techniques to enhance a visually appealing high frame rate, without incurring the bitrate and computational complexity common to high frame rate coding using conventional techniques. SVC skip slices—slices in which the slice_skip_flag in the slice header is set to a value of 1—require very few bits in the bitstream, thereby keeping the bitrate overhead very low. Also, when using an appropriate implementation, the computational requirements for coding an enhancement layer picture consisting entirely of skipped slices are almost negligible. In addition, skipped slices in an enhancement layer inherit motion information from the base layer(s), thereby minimizing, if not eliminating, the possibly bad correlation between nonlinear motion and linear interpolation. Further, the issue of radical brightness changes of a picture (or significant part thereof) does not exist, as the base layer is coded at full frame rate and can contain information related to the brightness change that can also be inherited by the enhancement layer.
    • 这里公开的技术和计算机可读介质包含被布置为利用现有的视频压缩技术来增强视觉上吸引人的高帧速率的指令,而不会产生使用常规技术的高帧率编码所共有的比特率和计算复杂度。 SVC跳过片段,其中片头部中的slice_skip_flag被设置为值1,在比特流中需要非常少的比特,从而保持比特率开销非常低。 此外,当使用适当的实现时,对完全由跳过的片组成的增强层图像的编码的计算要求几乎可以忽略不计。 另外,增强层中的跳过的片段从基层继承运动信息,从而最小化(如果不消除)非线性运动和线性内插之间的可能的不良相关性。 此外,由于基层以全帧速率编码并且可以包含与增强层也可以继承的亮度变化相关的信息,因此不存在图像(或其重要部分)的根本性亮度变化的问题。

    • The present invention provides, in one embodiment, a system and method for concealing video errors. The system includes a coding engine for processing each frame of a video signal to generate macroblocks, selecting a refresh interval based upon network communication parameters, and encoding one or more of the macroblocks as refresh intra-coded macroblocks based upon the selected refresh interval. The refresh intra-coded macroblocks are placed into discrete data packets for transmission across a network to one or more remote devices. Upon receiving other refresh intra-coded macroblocks from a remote device via the network, the coding engine decodes the received intra-coded macroblocks, and places the decoded macroblocks in a newly decoded video frame to be used as reference frame macroblocks for reducing video errors associated with prediction drift.
