Abstract

La presente descripción revela un método y un aparato para generar un filtro de imagen, y pertenece a un campo de la tecnología de procesamiento de imágenes. El método incluye: obtener una imagen de efecto seleccionada; obtener un grupo de imágenes similares usando la imagen de efecto, el grupo de imágenes similares incluye por lo menos una imagen similar que tiene una estructura similar a la de la imagen de efecto, pero sin efecto de filtro; calcular una relación de mapeo para transformar el grupo de imágenes similares en la imagen de efecto, y usar la relación de mapeo como el filtro de imagen. Al obtener el grupo de imágenes similares que tienen la estructura similar a la de la imagen de efecto, calcular la relación de mapeo para transformar el grupo de imágenes similares en la imagen de efecto, y usar la relación de mapeo como el filtro de imagen, se soluciona un problema que consiste en que una imagen procesada por el usuario empleando un filtro autodefinido obtenida mediante el ajuste de parámetros no pueda conseguir el efecto deseado por el usuario debido a una carencia de profesionalización, y se mejora una precisión del filtro de imagen autodefinido.
