CapsNet Regularization and its Conjugation with ResNet for Signature Identification

29 Jan 2021  ·  Mahdi Jampour, Saeid Abbaasi, Malihe Javidi ·

We propose a new regularization term for CapsNet that significantly improves the generalization power of the original method from small training data while requiring much fewer parameters, making it suitable for large input images. We also propose a very efficient DNN architecture that integrates CapsNet with ResNet to obtain the advantages of the two architectures. CapsNet allows a powerful understanding of the objects' components and their positions, while ResNet provides efficient feature extraction and description. Our approach is general, and we demonstrate it on the problem of signature identification from images. To show our approach superiority, we provide several evaluations with different protocols. We also show that our approach outperforms the state-of-the-art on this problem with thorough experiments on three publicly available datasets CEDAR, MCYT, and UTSig.
