Semantic segmentation is a prominent problem in scene understanding expressed as a dense labeling task with deep learning models being one of the main methods to solve it. Traditional training algorithms for semantic segmentation models produce less than satisfactory results when not combined with post-processing techniques such as CRFs. In this paper, we propose a method to train segmentation models using an approach which utilizes classification information in the training process of the segmentation network. Our method employs the use of classification network that detects the presence of classes in the segmented output. These class scores are then used to train the segmentation model. This method is motivated by the fact that by conditioning the training of the segmentation model with these scores, higher order features can be captured. Our experiments show significantly improved performance of the segmentation model on the CamVid and CityScapes datasets with no additional post processing.
