Abstract

In this paper, we propose a novel framework of Foreign Object Debris (FOD) classification combining scale-invariant feature transform (SIFT) feature and color feature. This system contains FOD detection subsystem, image quality assessment, control center and FOD recognition subsystem. The system not only achieves the goal of FOD detection, but also fulfills the task of FOD classification. We propose a mixed feature method that combines SIFT feature and color feature to extract FOD feature and use Support vector machine (SVM) or nearest neighbor (NN) to classify FOD image. Experiment results show that the proposed framework is effective and accurate.
