Abstract

Método de clasificación de tapones de corcho, a partir de imágenes de su superficie (26), que comprende: obtener a partir de las imágenes de sus fases (27) una imagen binaria mediante un solo valor umbral de grises; filtrado de "extracción de contornos y seguimiento'' de las anteriores imágenes (28); segmentación adaptativa para obtener un valor de grises umbral de defectos y fondo de la superficie lateral (29); erosión de la imagen digitalizada de la superficie lateral, utilizando un filtrado morfológico (g); filtrado adicional (e) con patrones de la imagen de la etapa anterior, para eliminar defectos triviales; digitalización referente a zonas con y sin defectos de las imágenes superior e inferior (30); erosión de las imágenes de la etapa anterior digitalizadas por medio de un filtrado morfológico; y clasificación del tapón (h).
