Abstract

SE OBTIENE UN RECTANGULO CIRCUNSCRITO DURANTE UNA PARTE DE LA IMAGEN CONTINUA NEGRA USANDO UNA SEÑAL DE IMAGEN DE DOS TONOS. SI SE DETERMINA (EN S105) QUE LA PARTE DE LA IMAGEN ES POSIBLEMENTE UNA QUE SE OBTENGA COMO RESULTADO DE LA ROTACION DEL OBJETO, SE COMPARAN LAS LONGITUDES DE LOS LADOS DE LA PARTE DE LA IMAGEN CON VALORES DE UMBRAL (EN S106 Y S108). SI SE DETERMINA (EN S105) QUE LA PARTE DE LA IMAGEN NO ES UNA QUE SE OBTENGA COMO RESULTADO DE LA ROTACION DEL OBJETO, LA ALTURA Y LA LONGITUD HORIZONTAL DEL RECTANGULO QUE SE CIRCUNSCRIBE SE COMPARAN CON LOS VALORES DE UMBRAL (EN S107 Y S108). ASI, SE DETERMINA (EN S115 Y S116) SI LA PARTE DE LA IMAGEN ES IDENTICA AL OBJETO O NO. SE PRODUCE UN HISTOGRAMA DE CROMACIDAD RGB PARA CADA UNA DE LAS REGIONES PEQUEÑAS DE UNA IMAGEN DE ENTRADA EN COLOR (EN S202A). CADA UNO DE LOS HISTOGRAMAS DE CROMACIDAD DE LAS REGIONES PEQUEÑAS SE COMPARA CON UNOS DE REFERENCIA (EN S202A). COMO RESULTADO DE LA COMPARACION, SE DA UN NUMERO DE IDENTIFICACION DELHISTOGRAMA DE REFERENCIA QUE TIENE LA MAYOR SIMILITUD A ESE DE LA REGION PEQUEÑA ENTRE AQUELLOS QUE CONSTITUYEN LA IMAGEN DE ENTRADA A LA REGION PEQUEÑA (EN S204). SE PRODUCE ASI UN HISTOGRAMA DE LOS NUMEROS DE IDENTIFICACION PARA LA ENTRADA DE LA IMAGEN EN COLOR (EN S204). EL HISTOGRAMA ASI PRODUCIDO SE USA PARA DETERMINAR (EN S205) CUAL DE ENTRE UNA PLURALIDAD DE OBJETOS ES IDENTICO A LA IMAGEN EN COLOR DE ENTRADA.
