Operation-level vision-based monitoring and documentation has drawn significant attention from construction practitioners and researchers. Our proposed method, named TD-CEDN, We develop a simple yet effective fully convolutional encoder-decoder network for object contour detection and the trained model generalizes well to unseen object classes from the same super-categories, yielding significantly higher precision than previous methods. solves two important issues in this low-level vision problem: (1) learning The final prediction also produces a loss term Lpred, which is similar to Eq. Given its axiomatic importance, however, we find that object contour detection is relatively under-explored in the literature. home. A complete decoder network setup is listed in Table. Owing to discarding the fully connected layers after pool5, higher resolution feature maps are retained while reducing the parameters of the encoder network significantly (from 134M to 14.7M).

W.Shen, X.Wang, Y.Wang, X.Bai, and Z.Zhang. Note that we use the originally annotated contours instead of our refined ones as ground truth for unbiased evaluation. Shen et al. The encoder-decoder network is composed of two parts: encoder/convolution and decoder/deconvolution networks. The above mentioned four methods[20, 48, 21, 22] are all patch-based but not end-to-end training and holistic image prediction networks. [42], incorporated structural information in the random forests. The proposed multi-tasking convolutional neural network did not employ any pre- or postprocessing step. Our network is trained end-to-end on PASCAL VOC with refined ground truth from inaccurate polygon annotations, yielding much higher precision in object contour detection than previous methods. synthetically trained fully convolutional network, DeepEdge: A Multi-Scale Bifurcated Deep Network for Top-Down Contour TLDR. abstract = "We develop a deep learning algorithm for contour detection with a fully convolutional encoder-decoder network.

Note that our model is not deliberately designed for natural edge detection on BSDS500, and we believe that the techniques used in HED[47] such as multiscale fusion, carefully designed upsampling layers and data augmentation could further improve the performance of our model. A novel semantic segmentation algorithm by learning a deep deconvolution network on top of the convolutional layers adopted from VGG 16-layer net, which demonstrates outstanding performance in PASCAL VOC 2012 dataset. The Pb work of Martin et al. 17 Jan 2017. Abstract We present a significantly improved data-driven global weather forecasting framework using a deep convolutional neural network (CNN) to forecast several basic atmospheric variables on a gl. This allows our model to be easily integrated with other decoders such as bounding box regression[17] and semantic segmentation[38] for joint training. A new method to represent a contour image where the pixel value is the distance to the boundary is proposed, and a network that simultaneously estimates both contour and disparity with fully shared weights is proposed. , A new 2.5 D representation for lymph node detection using random sets of deep convolutional neural network observations, in: International Conference on Medical Image Computing and Computer-Assisted Intervention, Springer, 2014, pp. semantic segmentation, in, H.Noh, S.Hong, and B.Han, Learning deconvolution network for semantic contour detection than previous methods. 13 papers with code Dive into the research topics of 'Object contour detection with a fully convolutional encoder-decoder network'.

B.Hariharan, P.Arbelez, L.Bourdev, S.Maji, and J.Malik. 0 benchmarks By combining with the multiscale combinatorial grouping algorithm, our method can generate high-quality segmented object proposals, which significantly advance the state-of-the-art on PASCAL VOC (improving average recall from 0.62 to 0.67) with a relatively small amount of candidates (~1660 per image). Long, R.Girshick, Microsoft COCO: Common objects in context. By combining with the multiscale combinatorial grouping algorithm, our method can generate high-quality segmented object proposals, which significantly advance the state-of-the-art on PASCAL VOC (improving average recall from 0.62 to 0.67) with a relatively small amount of candidates (1660 per image). Hariharan et al. We develop a deep learning algorithm for contour detection with a fully convolutional encoder-decoder network. Previous algorithms efforts lift edge detection to a higher abstract level, but still fall below human perception due to their lack of object-level knowledge. Different from HED, we only used the raw depth maps instead of HHA features[58]. We first examine how well our CEDN model trained on PASCAL VOC can generalize to unseen object categories in this dataset. Detection and Beyond. We also experimented with the Graph Cut method[7] but find it usually produces jaggy contours due to its shortcutting bias (Figure3(c)). Encoder-decoder architectures can handle inputs and outputs that both consist of variable-length sequences and thus are suitable for seq2seq problems such as machine translation. (up to the fc6 layer) and to achieve dense prediction of image size our decoder is constructed by alternating unpooling and convolution layers where unpooling layers re-use the switches from max-pooling layers of encoder to upscale the feature maps. Different from previous low-level edge detection, our algorithm focuses on detecting higher-level object contours. Lin, M.Maire, S.Belongie, J.Hays, P.Perona, D.Ramanan, Different from previous low-level edge detection, our algorithm focuses on detecting higher-level object contours. Concerned with the imperfect contour annotations from polygons, we have developed a refinement method based on dense CRF so that the proposed network has been trained in an end-to-end manner.

We compared the model performance to two encoder-decoder networks; U-Net as a baseline benchmark and to U-Net++ as the current state-of-the-art segmentation fully convolutional network. Given that over 90% of the ground truth is non-contour. We develop a deep learning algorithm for contour detection with a fully convolutional encoder-decoder network. Compared with CEDN, our fine-tuned model presents better performances on the recall but worse performances on the precision on the PR curve. Recent works, HED[19] and CEDN[13], which have achieved the best performances on the BSDS500 dataset, are two baselines which our method was compared to. loss for contour detection.

Lindeberg, The local approaches took into account more feature spaces, such as color and texture, and applied learning methods for cue combination[35, 36, 37, 38, 6, 1, 2]. Complete survey of models in this eld can be found in . Figure8 shows that CEDNMCG achieves 0.67 AR and 0.83 ABO with 1660 proposals per image, which improves the second best MCG by 8% in AR and by 3% in ABO with a third as many proposals. Different from previous . Different from previous low-level edge detection, our algorithm focuses on detecting higher-level object contours. The ground truth contour mask is processed in the same way. To address the problem of irregular text regions in natural scenes, we propose an arbitrary-shaped text detection model based on Deformable DETR called BSNet.
