Transfer of a high-level knowledge in HoughNet neural network

Proc. SPIE 11433, Twelfth International Conference on Machine Vision (ICMV 2019), 1143322 (31 January 2020); https://doi.org/10.1117/12.2559454

In this paper, we study the recently introduced neural network architecture HoughNet for the ability to accumulate transferable high-level features. The main idea of that neural network is to use convolutional layers separated with Fast Hough Transform layers to enable an analysis of complex non-linear statistics along different lines. We show that different convolutional blocks in this neural network have essentially different purposes. While initial features extracting is task-specific, the main part of the neural network operates with high-level features and do not require re-training in order to be applied to data from a different domain. To prove our statement, we two sets of the images with different origins and demonstrate Transfer Learning presence in the neural network except for the first layers which are highly task-specific.
