Abstract: In this paper we study different 3D features in cork material. We do this in order to solve a classification problem existing in the cork industry: the cork stopper/disk quality classification. Cork Quality Standard sets seven different cork quality classes for cork stopper classification. These classes are based on a complex combination of cork stopper defects. In previous studies we only analysed those features that could be detected/acquired with a 2D camera. In this study we work in a 3D environment, in order to extract those features that we could not be extracted in a 2D approach. As a conclusion we can say that the most important 3D cork quality detection feature takes into account dark and deep cork areas (usually, these areas indicate deep and important defects). Furthermore, the 3D features have widely improved the results obtained by similar features with a 2D approach, due to the 3D approach includes more information. This fact allows us to extract more complex features, as well as improve the classification results. (More)
