摘要： Web-based authentication includes receiving a packet in a network switch having at least one associative store configured to forward packet traffic to a first one or more processors of the switch that are dedicated to cryptographic processing if a destination port of the packet indicates a secure transport protocol, and to a second one or more processors of the switch that are not dedicated to cryptographic processing if the destination port does not indicate a secure transport protocol. If a source of the packet is an authenticated user, the packet is forwarded via an output port of the switch, based on the associative store. If the source is an unauthenticated user, the packet is forwarded to the first one or more processors if the destination port indicates a secure transport protocol, and to the second one or more processors if the destination port does not indicate a secure transport protocol.

摘要： A signal classifying method and apparatus are disclosed. The signal classifying method includes: obtaining a spectrum fluctuation parameter of a current signal frame determined as a foreground frame, and buffering the spectrum fluctuation parameter; obtaining a spectrum fluctuation variance of the current signal frame according to spectrum fluctuation parameters of all buffered signal frames, and buffering the spectrum fluctuation variance; and calculating a ratio of signal frames whose spectrum fluctuation variance is above or equal to a first threshold to all the buffered signal frames, and determining the current signal frame as a speech frame if the ratio is above or equal to a second threshold or determining the current signal frame as a music frame if the ratio is below the second threshold. In the embodiments of the present invention, the spectrum fluctuation variance of the signal is used as a parameter for classifying the signals, and a local statistical method is applied to decide the type of the signal. Therefore, the signals are classified with few parameters, simple logical relations and low complexity.

摘要： A method for tone mapping high dynamic range images for display on low dynamic range displays wherein high dynamic range images are first accessed. The high dynamic range images are divided the into different regions such that each region is represented by a matrix, where each element of the matrix is a weight or probability of a pixel value. An exposure of each region is determined or calculated by estimating an anchor point in each region such that most pixels in each region are mapped to mid grey and the anchor points are adjusted to a key of the images to preserve overall brightness. The regions are then placed or mapped to zones and exposure values are applied to the regions responsive to the weight or probability. The regions are fused together to obtain a final tone mapped image.
