  • Publication number: 20120320234
    Abstract: A device and a method for predicting photograph timing. First, a detection step is performed. Then, a face determination step is performed to determine whether or not a face is shown. A face-classifying step is then performed. If a detected image is a non-front face, a difference generation step is then performed. A difference determination step is performed when a plurality of differences are obtained to determine whether or not the sequentially adjoined differences are reduced, wherein if the sequentially adjoined differences are reduced, a photographing timing is predicted according to a reduction degree of the differences. As a result, the probability of successfully photographing the front face can be enhanced. In addition, a training database that has both front face information and non-front face information can be utilized. As a result, it is not easy to determine the non-front face as the front face incorrectly.

  • Patent number: 7826384
    Abstract: Methods and apparatus for negotiating bearer control parameters using property sets. A property set is a specific set of default parameters or “properties” to be used for a given bearer channel type in an integrated node. Property set information can be passed between integrated nodes (301, 302) in a multimedia packet network (305). In many cases, a parameter negotiation can be completed quickly after the originating node sends a setup message including a list of one or more property sets and one or more requested parameters. In all cases, the bearer type and bearer parameters are determined based on capabilities of the originating and terminating nodes. The invention provides a way for existing signaling links using bearer independent call control (BICC), or session initiation protocol (SIP), or H.245, or similar protocols with a way to negotiate more bearer types and parameters without significantly increasing the bandwidth needed for the negotiation, or requiring nodes to be provisioned.
