Deepcontour: A deep convolutional feature learned by positive-sharing We also integrated it into an object detection and semantic segmentation multi-task model using an asynchronous back-propagation algorithm. Different from our object-centric goal, this dataset is designed for evaluating natural edge detection that includes not only object contours but also object interior boundaries and background boundaries (examples in Figure6(b)). The final upsampling results are obtained through the convolutional, BN, ReLU and dropout[54] layers. Figure7 shows that 1) the pretrained CEDN model yields a high precision but a low recall due to its object-selective nature and 2) the fine-tuned CEDN model achieves comparable performance (F=0.79) with the state-of-the-art method (HED)[47]. We compared our method with the fine-tuned published model HED-RGB.

As a result, our method significantly improves the quality of segmented object proposals on the PASCAL VOC 2012 validation set, achieving 0.67 average recall from overlap 0.5 to 1.0 with only about 1660 candidates per image, compared to the state-of-the-art average recall 0.62 by original gPb-based MCG algorithm with near 5140 candidates per image.

Among those end-to-end methods, fully convolutional networks[34] scale well up to the image size but cannot produce very accurate labeling boundaries; unpooling layers help deconvolutional networks[38] to generate better label localization but their symmetric structure introduces a heavy decoder network which is difficult to train with limited samples. We evaluate the trained network on unseen object categories from BSDS500 and MS COCO datasets[31], Due to the asymmetric nature of image labeling problems (image input and mask output), we break the symmetric structure of deconvolutional networks and introduce a light-weighted decoder. of indoor scenes from RGB-D images, in, J.J.
