Abstract

Rotation symmetry is a salient visual clue in describing and recognizing an object or a structure in an image. Recently, various rotation symmetry detection methods have been proposed based on key point feature matching scheme. However, hand crafted representation of rotation symmetry structure has shown limited performance. On the other hand, deep learning based approach has been rarely applied to symmetry detection due to the huge diversity in the visual appearance of rotation symmetry patterns. In this work, we propose a new framework of convolutional neural network based on two core layers: rotation invariant convolution (RI-CONV) layer and symmetry structure constrained convolution (SSC-CONV) layer. Proposed network learns structural characteristic from image samples regardless of their appearance diversity. Evaluation is conducted on 32,000 images (after augmentation) of our rotation symmetry classification data set.
