Automatic control of visual parameters in video processing

Abstract: Embodiments of the invention are directed to a system and method for controlling visual parameters of a capturing device to minimize clipping and saturation according to predefined parameters The method may include processing pixel values of a current input frame of a received video signal captured by a capturing device; accumulating processing results of the current input frame to processing results of one or more previous input frames and calculating a desired dynamic range based on pre-determined user parameters The processing may further include checking if the accumulated results are within the desired dynamic range and determining if adjustment is desired If the accumulated results are not within the desired dynamic range, adjusting visual parameters for a subsequent input frame, by controlling the capturing device and if the accumulated results are within the desired dynamic range maintaining current visual parameters of the current input frame for the subsequent input frame

Method and apparatus for large vocabulary continuous speech recognition using a hybrid phoneme-word lattice

Abstract: A method and apparatus combining the advantages of phonetic search such as the rapid implementation and deployment and medium accuracy, comprising steps and components for receiving the audio signal captured in the call center environment, extracting a multiplicity of feature vectors from the audio signal, creating a phoneme lattice from the multiplicity of feature vectors wherein the phoneme lattice comprising one or more allophone and each allophone comprising two or more phonemes, creating a hybrid phoneme-word lattice from the phoneme lattice and extracting the word by analyzing the hybrid phoneme-Word lattice.

Prediction interactive vocla response

Abstract: A method for responding to calls in an Interactive Voice Response system (IVR) of an organization, the method comprising receiving in an IVR a call from a customer of the organization, activating a response in the IVR based at least on former interactions with the organization, and wherein the IVR is a computerized system comprising at least one processor, and an apparatus for performing the same.

Method and system for behavioral and risk prediction in networks using automatic feature generation and selection using network topolgies

Abstract: A system or method may include receiving, by a processor, data describing a network, wherein the network includes a plurality of entities and links describing relationships between the plurality of entities. The method may further include identifying a set of seed entities from the plurality of entities based on predefined rules. The method may further include generating a set of sub-networks based on the set of identified seed entities, wherein each of the sub-networks may include one or more other entities of the plurality of entities having at least one link to the at least one seed entity. The method may further include calculating a risk score for each of the generated sub-networks.

Method and system for selecting a recording route in a multi-media recording environment

Abstract: Device and method for receiving information from one or more media providers capable of transmitting a media session and from one or more media recorders capable of recording the media session and selecting one of the recorders for recording the media session based on the received information and a predetermined set of rules.
