Abstract

In this paper, we propose an attention-based dynamic graph CNN method for point cloud classification. We introduce an efficient channel attention module into each edge convolution block of dynamic graph CNN (DGCNN) to obtain more discriminative and stable features. Our experimental results show that, compared with DGCNN, our method improves not only the classification accuracy but also the stability.
