  • Patent number: 6400828
    Abstract: The identification of hidden data, such as feature-based control points in an image, from a set of observable data, such as the image, is achieved through a two-stage approach. The first stage involves a learning process, in which a number of sample data sets, e.g. images, are analyzed to identify the correspondence between observable data, such as visual aspects of the image, and the desired hidden data, such as the control points. Two models are created. A feature appearance-only model is created from aligned examples of the feature in the observed data. In addition, each labeled data set is processed to generate a coupled model of the aligned observed data and the associated hidden data. In the second stage of the process, the modeled feature is located in an unmarked, unaligned data set, using the feature appearance-only model. This location is used as an alignment point and the coupled model is then applied to the aligned data, giving an estimate of the hidden data values for that data set.

  • Patent number: 6377529
    Abstract: A method is disclosed for compensating for intersymbol interference on an optical disc. The method includes measuring an intersymbol linear transfer function. The intersymbol linear transfer function substantially describes a linear portion of the effect of intersymbol interference on an optically detected read signal from an optical disc. A partial response target frequency response is divided by the intersymbol linear transfer function to obtain a linear equalization filter response. A read signal from the optical disc is convolved with the linear equalization filter response. This results in the read signal being equalized and containing a controlled partial-response target intersymbol interference. There is also disclosed a method of compensating utilizing a decision feedback equalizer where the target frequency response is either a partial-response or a zero-forcing response.

  • Patent number: 6317775
    Abstract: Disclosed is a system and method for distributing connections among a plurality of servers at an Internet site. All connections are made to a single IP address and a local director selects the server from among the plurality of servers which is to receive the connection. Thus, the DNS server is not relied upon to distribute connections, and the connection distribution scheme is not avoided when DNS is bypassed. In one embodiment, a session distribution scheme is implemented such that connections are distributed to the server in the group of servers which has the fewest connections of the group. In other embodiments, other session distribution schemes which route connections based on the predicted response times of the servers or according to a round robin scheme are used.

  • Patent number: 6298063
    Abstract: A system and method are disclosed for redirecting a connection from a first server having a first server IP address. Incoming SYN packets sent from a client are intercepted. The SYN packets have a destination IP address corresponding to the connection and the SYN packets are sent from the client for the purpose of establishing the connection, which is supported by the first server. The number of incoming SYN packets sent from the client to the first server is monitored and it is determined whether the number of unanswered SYN packets sent by the client to the first server exceeds a ditched connection threshold number of unanswered SYN packets. The destination IP address of intercepted incoming SYN packets is changed for the connection received after determining that the number of unanswered SYN requests sent by the client to the first server exceeds a ditched connection threshold number of unanswered SYN requests to the destination IP address of a second server.

  • Patent number: 6298381
    Abstract: The present invention relates to a system and method for information retrieval related to a service. According to an embodiment of the present invention, two separate types of packets may be received to indicate information which is required. One type of packet is intended for information which may be directly looked up in a table, such as a routing table, while the other type of packet is intended for information which requires calculating or measuring metrics. Accordingly, if information which may be directly looked up in a routing table is requested along with information regarding metrics which need to be measured or calculated, then the routing table information is sent as soon as the requested information is looked up and the measured metric information is sent later when the requested metric is measured.
