Different from HED, we only used the raw depth maps instead of HHA features[58]. However, because of unpredictable behaviors of human annotators and limitations of polygon representation, the annotated contours usually do not align well with the true image boundaries and thus cannot be directly used as ground truth for training. [19] and Yang et al. As a result, the trained model yielded high precision on PASCAL VOC and BSDS500, and has achieved comparable performance with the state-of-the-art on BSDS500 after fine-tuning. This paper proposes a simple and scalable detection algorithm that improves mean average precision (mAP) by more than 30% relative to the previous best result on VOC 2012 -- achieving a mAP of 53.3%. The convolutional layer parameters are denoted as conv/deconvstage_index-receptive field size-number of channels. D.R. Martin, C.C. Fowlkes, and J.Malik.
