Abstract
EL METODO Y SISTEMA DE LA INVENCION INCLUYE UN ALGORITMO DE CALCULO DE ALTA VELOCIDAD (30) PARA LA ROTACION DE IMAGENES ALMACENADAS EN LA MEMORIA DE UN ORDENADOR (26), TALES COMO LAS CAPTURADAS POR UNA CAMARA CCD (22). LA PRESENTE INVENCION SE PUEDE UTILIZAR CON UN LECTOR DE RECONOCIMIENTO OPTICO DE CARACTERES (OCR) SOBRE LA CINTA (10) QUE CAPTURA UNA IMAGEN DE PIXELS DE LA SUPERFICIE DE UNA PARCELA (14) CUANDO SE MUEVE A LO LARGO DE UNA CINTA TRANSPORTADORA (12). LA REALIZACION PRACTICA PRESENTADA PROPORCIONA UN METODO Y UN SISTEMA PARA OBTENER UNA IMAGEN DE SALIDA CODIFICADA EN COORDENADA DIFERENCIAL A PARTIR DE UNA IMAGEN DE ENTRADA CODIFICADA EN COORDENADA DIFERENCIAL, DONDE LA IMAGEN DE SALIDA (17 ) ES UNA VERSION GIRADA DE LA IMAGEN DE ENTRADA. SE UTILIZA UNA SECUENCIA DE REPRESENTACION DE PIXEL, PREDEFINIDA PARA UN ANGULO DE ROTACION CON UNA TANGENTE RACIONAL, PARA REPRESENTAR LOS DATOS DE PIXEL DE IMAGEN. LA CONFIGURACION DE LOS DATOS DE PIXEL DE IMAGEN EMPLEANDO UNA SECUENCIA DE CONFIGURACION DE PIXEL PREDEFINIDA PERMITE LA ROTACION SIN CALCULOS DE PUNTOS FLOTANTES Y LA UTILIZACION DE UNA TECNICA DE CONFIGURACION INVERSA DE PIXEL PARA CONFIGURAR LAS EJECUCIONES DE SALIDA A PARTIR DE UNA IMAGEN DE ENTRADA, CON EL FIN DE EVITAR LA FORMACION DE HUECOS O RESTOS EN LA IMAGEN DE SALIDA. EL METODO DE LA INVENCION, ADAPTA LAS EJECUCIONES DE SALIDA CONFIGURADAS PARA PRESERVAR LA RELACION DE ASPECTO DE LA IMAGEN GIRADA. EL METODO DE LA INVENCION SELECCIONA EL ORDEN EN EL QUE PROCESAR LOS ELEMENTOS DE ENTRADA DE LA TABLA DE ENTRADAS EN COORDENADA DIFERENCIAL, PARA CREAR DIRECTAMENTE UNA TABLA DE SALIDA CODIFICADA EN COORDENADA DIFERENCIAL.
