Details for method 'Adelaide_context'

 

Method overview

name Adelaide_context
challenge pixel-level semantic labeling
details We explore contextual information to improve semantic image segmentation. Details are described in the paper. We trained contextual networks for coarse level prediction and a refinement network for refining the coarse prediction. Our models are trained on the training set only (2975 images) without adding the validation set.
