Inter-Region Affinity Distillation for Road Marking Segmentation

CVPR 2020poster

We study the problem of distilling knowledge from a large deep teacher network to a much smaller student network for the task of road marking segmentation. In this work, we explore a novel knowledge distillation (KD) approach that can transfer 'knowledge' on scene structure more effectively from a t…

LiteFlowNet3: Resolving Correspondence Ambiguity for More Accurate Optical Flow Estimation

ECCV 2020poster

Deep learning approaches have achieved great success in addressing the problem of optical flow estimation. The keys to success lie in the use of cost volume and coarse-to-fine flow inference. However, the matching problem becomes ill-posed when partially occluded or homogeneous regions exist in imag…

LiteFlowNet: A Lightweight Convolutional Neural Network for Optical Flow Estimation

CVPR 2018poster

FlowNet2, the state-of-the-art convolutional neural network (CNN) for optical flow estimation, requires over 160M parameters to achieve accurate flow estimation. In this paper we present an alternative network that attains performance on par with FlowNet2 on the challenging Sintel final pass and KIT…
