A framework of extracting multi-scale features using multiple convolutional neural networks

Most works related to convolutional neural networks (CNN) use the traditional CNN framework which extracts features in only one scale. We propose multi-scale convolutional neural networks (MSCNN) which can not only extract multi-scale features but also solve the issues of the previous methods which use CNN to extract multi-scale features. With the assumption of label-inheritable (LI) property, we also propose a method to generate exponentially more training examples for MSCNN from the given training set. Our experimental results show that MSCNN outperforms both the state-of-the-art methods and the traditional CNN framework on artist, artistic style, and architectural style classification, supporting that MSCNN outperforms the traditional CNN framework on the tasks which at least partially satisfy LI property.
