  • Patent number: 7203343
    Abstract: A system and method for finding one or more target biometric samples that are similar to or match a query biometric sample. A query feature vector is generated from a query biometric vector. The query biometric vector represents the query biometric sample as a set of characteristics. The characteristics are either invariable or variable. The query feature vector comprises a plurality of features which are derived from the query biometric vector using a process that includes canonicalization of the characters in the biometric vector. The query feature vector is compared to a plurality of similarly created target feature vectors, each target feature vector representing a respective target biometric sample. A target biometric sample is a potential match to the query biometric sample when a threshold number of features in the corresponding target feature vector are identical to features in the query biometric vector.

  • Patent number: 4761691
    Abstract: A video recording system employs an editing device to communicate schedules of instructions to a videotape recorder control system which, in turn, communicates selected ones of the instructions from the schedules to a time-base corrector so that the time-base corrector automatically controls and adjusts video signal parameters at the output of the videotape recorder in accordance with an appropriate one of the schedules. Operation of the system includes the steps of storing schedules of instructions in the editing device, communicating the schedules of instructions to a videotape recorder control system connected to a time-base corrector, storing time lines of the instructions in the videotape recorder control system, and operating the time-base corrector to manipulate video signal information at the output of a recorder mechanism according to the time line schedules.

  • Patent number: 4758892
    Abstract: Video channel combines are produced by digitally processing binary numbers representing values of video image information in multiple channels, for corresponding points in a display of the resulting composite video image. The binary numbers are combined in the course of processing in response to processed key signals which determine a preselected percentage of each binary number's value, to produce new binary numbers. After summation, the latter represent composite video image values to be displayed at the same temporal and spatial locations of the display of the composite video image. Total percentages resulting from the summation of all numbers for each composite video image value, including numbers corresponding to percentage of background video, is equal to 100%.
