Abstract

Se describe una tecnica eficiente para determinar una porcion de un documento que corresponde a una imagen capturada. Cuando un usuario emplea una pluma para crear una carrera e un documento, las imagenes del documento son capturadas por una camara montada sobre la pluma. Aunque la ubicacion de algunas de las imagenes sera determinada a partir de, por ejemplo, un analisis de un patron en el documento que es capturado por la imagen o una comparacion de pixel por pixel de la imagen con el documento, la ubicacion de otras imagenes sera determinada segmentando la secuencia de imagenes en grupos que corresponden a la forma de la carrera. La informacion con relacion a las imagenes localizadas en un segmento despues puede ser empleada para determinar la posicion de imagenes no localizadas en el segmento. Por ejemplo, una region de busqueda de documento para una imagen no localizada puede ser establecida basandose en la posicion de una imagen localizada previa y una velocidad o aceleracion maxima de la pluma. La rotacion y escala de la imagen no localizada son estimadas como igual a la imagen localizada, y la imagen no localizada es deformada utilizando la rotacion y escala. Despues se puede hacer una comparacion de pixel por pixel entre la imagen no localizada deformada y la region de busqueda de documento. Ademas, si la imagen no localizada deformada es comparada exitosamente, los parametros de transformacion de la imagen pueden ademas ser definidos.
