Abstract

Un método de corrección de ondulación de página en libros registrados por exploración electrónica implementado por computadora para corregir la distorsión en una imagen de una página incluye identificar en conjunto de palabras de alta calidad (HQ) en regiones no distorsionadas de una o más imágenes de páginas que tengan contenidos relaciona con el contenido de la página. Al menos una palabra distorsionada de la imagen de la página es identificada, de modo que cada palabra distorsionada corresponda a una palabra de alta calidad del conjunto. Se genera una función de transformación global para aplicarse a la imagen de la página para transformar la palabra distorsionada en su palabra de alta calidad correspondiente. La función de transformación global es aplicada a los píxeles de la imagen de la página.
