Abstract
Se proporcionan un método y dispositivo para extracción de región en la descripción, la cual pertenece al campo técnico de procesamiento de imágenes. El método puede comprender: obtener una posición de región de una primera región de información en una imagen de credencial; determinar una segunda región de información de acuerdo con la posición de región de la primera región de información; y segmentar la segunda región de información para obtener al menos una zona de caracteres. Los problemas de que en la técnica relacionada a la región de que el reconocimiento de algunas regiones de información en una imagen de credencial fotografiada directamente es difícil de implementar y la colocación de algunas regiones de información es imprecisa, pueden resolverse. Los siguientes efectos pueden alcanzarse en que determinan la segunda información de región besándose en la posición de región de la primera región de información en una imagen de credencial y segmentar la segunda región de información, de esta manera colocando de forma precisa la segunda región de información y reconociendo la zona de caracteres en la segunda región de información.
