Abstract: An image recognition system (10) is provided for identifying predetermined individual members of a viewing audience in a monitored area. A pattern image signature is extracted (98) and is stored (100) corresponding to each predetermined individual member of the viewing audience to be identified. An audience scanner (12) includes audience locating circuitry (30, 18) for locating individual audience members in the monitored area. A video image (28A, 22A) is captured (12, 18, 22) for each of the located individual audience members in the monitored area. A pattern image signature is extracted (110) from the captured image. The extracted pattern image signature is compared (112, 114) with each of the stored pattern image signatures (100) to identify a particular one of the predetermined audience members. These steps are repeated to identify all of the located individual audience members in the monitored area.

Abstract: In a passive identification apparatus for identifying a predetermined individual member of a television viewing audience in a monitored viewing area, a video image of a monitored viewing area is captured. A template matching score is provided for an object in the video image. A Eigenface recognition score is provided for an object in the video image. These scores may be provided by comparing objects in the video image to reference files. The template matching score and the Eigenface recognition score are fused to form a composite identification record from which a viewer may be identified. Body shape matching, viewer tracking, viewer sensing, and/or historical data may be used to assist in viewer identification. The reference files may be updated as recognition scores decline.

Abstract: An image recognition system (10) and method are provided for identifying a pattern of a plurality of predetermined patterns in a video image. A plurality of feature image signatures are extracted (84) and the stored (86) corresponding to each of the plurality of predetermined patterns. A universal feature image signature is extracted (84) and is stored (88) that includes each of the stored feature image signatures. A predetermined series of portions of a captured video image (28A) is sequentially compared (100, 102) with the universal feature image signature to identify matching portions. Each of the identified matching video image portions is compared (104, 108) with the stored feature image signatures to identify the predetermined pattern.

Abstract: IMAGE RECOGNITION AUDIENCE MEASUREMENT SYSTEM AND METHOD An image recognition method and system are provided for identifying predetermined individual members of a viewing audience in a monitored area. A pattern image signature is stored corresponding to each predetermined individual member of the viewing audience to be identified. An audience scanner includes audience locating circuitry for locating individual audience members in the monitored area. A video image is captured for each of the located individual audience members in the monitored area. A pattern image signature is extracted from the captured image. The extracted pattern image signature is compared with each of the stored pattern image signatures to identify a particular one of the predetermined audience members. These steps are repeated to identify all of the located individual audience members in the monitored area.

Abstract: PROGRAM IDENTIFICATION METHOD AND APPARATUS A method and apparatus for identifying programs such as television programs received from various sources detects the occurrence of predetermined events such as scene changes in a video signal and extracts a signature from the video signal. the signatures and the times of occurrence of the signatures are stored and subsequently compared with reference signatures to identify the program. The signatures may be compared in pairs to increase resolution, and the time interval between events or signatures may also be used to identify the program, either by themselves or in conjunction with the signatures.

Abstract: UN METODO Y UN APARATO PARA IDENTIFICAR PROGRAMAS EMITIDOS REPETITIVAMENTE, TALES COMO ANUNCIOS COMERCIALES EMITIDOS EN RADIO Y TELEVISION, DETECTA LA OCURRENCIA DE EVENTOS PREDETERMINADOS EN UNA SE AL DE VIDEO Y/O EN UNA SE AL DE AUDIO, DETECTA UNA CONDICION DE ESTABILIDAD Y EXTRAE UNA IDENTIFICACION DE LA SE AL DE VIDEO Y/O AUDIO. LAS IDENTIFICACIONES Y LOS TIEMPOS DE OCURRENCIA DE LAS IDENTIFICACIONES SON ALMACENADOS Y COMPARADOS POSTERIORMENTE CON IDENTIFICACIONES DE REFERENCIA PARA IDENTIFICAR EL PROGRAMA Y EL TIEMPO DE SU EMISION. LAS IDENTIFICACIONES DE REFERENCIA PUEDEN OBTENERSE IDENTIFICANDO CARACTERISTICAS EXTRAIDAS REPETITIVAMENTE, NO IDENTIFICADAS, Y ORDENANDO UN REGISTRO DE LAS SE ALES DE VIDEO Y/O AUDIO PARA PERMITIR AL USUARIO DEL SISTEMA LA IDENTIFICACION DEL PROGRAMA NO IDENTIFICADO EMITIDO Y EL ALMACENAMIENTO DE LAS IDENTIFICACIONES ANTERIORMENTE SIN IDENTIFICAR COMO CARACTERISTICAS ADICIONALES DE REFERENCIA EN MEMORIA.
