Object Bounding Transformed Network for End-to-End Semantic Segmentation

In recent years, numerous studies of the use of a Fully Convolutional Network (FCN) for image semantic segmentation have been published. This work introduces an end-to-end Object Bounding Transformed Network (OBTNet) which combines the advantages of the Object Boundary Guided (OBG) and Doman Transform (DT). OBG is an object boundary based approach that increases the integrity of object shape. Based on OBG, we propose an Object Boundary Network (OBN) as the object region and object boundary generator. In addition, our system achieves object region preserving and object boundary preserving by employing DT. The proposed system uses the pretrained multi-scale ResNet101 as the base network and uses multi-scale atrous convolution to preserve the dimensions of the feature map, increasing the accuracy of semantic segmentation. Experiments show that our system yielded a mean IOU of 77.74% and outperformed the baseline model on the VOC2012 test set.
