Abstract

Se proporcionan un método y dispositivo para identificar regiones en la descripción, el cual pertenece al campo técnico de procesamiento de imágenes. El método incluye: obtener la posición de área de la región facial en una imagen de identificación; determinar al menos una región de información con base en la posición de área de la región facial; y segmentar la región de información para obtener al menos una región de carácter. Puede resolver los problemas en la técnica relacionada en la que es difícil identificar algunas regiones de información en la imagen de identificación obtenida directamente al fotografiar y en los que la ubicación de algunas regiones de información son inadecuadas, y puede lograr los efectos de la ubicación de las regiones de información de manera precisa e identificar la región de carácter en la región de información de manera precisa al determinar las otras regiones de información a través de la posición de área de la región facial en la imagen de identificación y al segmentar las otras regiones de información.
