Abstract

La presente divulgación divulga un método y dispositivo de segmentación de imagen perteneciente al campo del procesamiento de imágenes; el método de segmentación de imagen comprende: se establece un modelo de prominencia de una imagen; un punto muestra de primer plano y un punto muestra de fondo de una imagen son adquiridos de acuerdo con el modelo de prominencia; un modelo de clasificación de primer plano y de fondo es establecido de acuerdo con el modelo de prominencia así como el punto muestra de primer plano y el punto muestra de fondo; la imagen es segmentada de acuerdo con un algoritmo de corte de gráfico predefinido, y específicamente la imagen es segmentada de acuerdo con el algoritmo de corte de gráfico predefinido utilizando el modelo de clasificación de primer plano y de fondo y la información de borde relacionada con los píxeles; un modelo de clasificación de primer plano y de fondo es establecido al determinar automáticamente un punto muestra de primer plano y un punto muestra de fondo y al combinar un modelo de prominencia, y la segmentación de imagen se logra utilizando el modelo de clasificación de primer plano y de fondo; dicho problema en las tecnologías relacionadas se resuelve en que un usuario necesita seleccionar de manera manual y aproximada el punto muestra de primer plano y el punto muestra de fondo y por lo tanto la eficiencia de la segmentación es baja para segmentar un número grande de imágenes; se realiza la selección automática de muestras y se mejora la precisión de la clasificación.
