Compare Stereo Patches Using Atrous Convolutional Neural Networks
2018
In this work, we address the task of dense stereo matching with Convolutional Neural Networks (CNNs). Particularly, we focus on improving matching cost computation by better aggregating contextual information. Towards this goal, we advocate to use atrous convolution, a powerful tool for dense prediction task that allows us to control the resolution at which feature responses are computed within CNNs and to enlarge the receptive field of the network without losing image resolution and requiring learning extra parameters. Aiming to improve the performance of atrous convolution, we propose different frameworks for further boosting performance. We evaluate our models on KITTI 2015 benchmark, the result shows that we achieve on-par performance with fewer post-processing methods applied.
