In this work, we study the problem of line segment detection. In the recent studies of this problem, it was shown that neural network-based methods are able to outperform classical algorithms in accuracy, yet high computational complexity of neural networks limits their usage in real-world applications. In our work, we propose to fuse a neural network with a classical algorithm to compensate their flaws, by (i) feeding into the network not only an image, but also classical algorithm’s output and (ii) by combining their predictions. We expect these modifications to simplify the problem faced by the neural network, resulting in higher accuracy in smaller network. Proposed method provides 0.72 and 0.66 F – measure on Wireframe and York datasets respectively with 14 FPS on CPU.
