Considering that the dataset was annotated by multiple individuals independently, as samples illustrated in Fig. When the trained model is sensitive to the stronger contours, it shows a better performance on precision but a poor performance on recall in the PR curve. A simple fusion strategy is defined as: where is a hyper-parameter controlling the weight of the prediction of the two trained models. To automate the operation-level monitoring of construction and built environments, there have been much effort to develop computer vision technologies. This work proposes a novel yet very effective loss function for contour detection, capable of penalizing the distance of contour-structure similarity between each pair of prediction and ground-truth, and introduces a novel convolutional encoder-decoder network. 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). Hosang et al. [20] proposed a N4-Fields method to process an image in a patch-by-patch manner. This is a tensorflow implimentation of Object Contour Detection with a Fully Convolutional Encoder-Decoder Network (https://arxiv.org/pdf/1603.04530.pdf) . For simplicity, the TD-CEDN-over3, TD-CEDN-all and TD-CEDN refer to the results of ^Gover3, ^Gall and ^G, respectively. Image labeling is a task that requires both high-level knowledge and low-level cues. [3], further improved upon this by computing local cues from multiscale and spectral clustering, known as, analyzed the clustering structure of local contour maps and developed efficient supervised learning algorithms for fast edge detection. and the loss function is simply the pixel-wise logistic loss. We develop a deep learning algorithm for contour detection with a fully convolutional encoder-decoder network. Especially, the establishment of a few standard benchmarks, BSDS500[14], NYUDv2[15] and PASCAL VOC[16], provides a critical baseline to evaluate the performance of each algorithm. Unlike skip connections 3.1 Fully Convolutional Encoder-Decoder Network. Edge detection has a long history. Zhu et al. aware fusion network for RGB-D salient object detection. 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. Observing the predicted maps, our method predicted the contours more precisely and clearly, which seems to be a refined version. A tensorflow implementation of object-contour-detection with fully convolutional encoder decoder network - GitHub - Raj-08/tensorflow-object-contour-detection: A tensorflow implementation of object-contour-detection with fully convolutional encoder decoder network They assumed that curves were drawn from a Markov process and detector responses were conditionally independent given the labeling of line segments. We also found that the proposed model generalizes well to unseen object classes from the known super-categories and demonstrated competitive performance on MS COCO without re-training the network. A contour-to-saliency transferring method to automatically generate salient object masks which can be used to train the saliency branch from outputs of the contour branch, and introduces a novel alternating training pipeline to gradually update the network parameters. Being fully convolutional, our CEDN network can operate on arbitrary image size and the encoder-decoder network emphasizes its asymmetric structure that differs from deconvolutional network[38]. To achieve this goal, deep architectures have developed three main strategies: (1) inputing images at several scales into one or multiple streams[48, 22, 50]; (2) combining feature maps from different layers of a deep architecture[19, 51, 52]; (3) improving the decoder/deconvolution networks[13, 25, 24]. CVPR 2016: 193-202. a service of . A deep learning algorithm for contour detection with a fully convolutional encoder-decoder network that generalizes well to unseen object classes from the same supercategories on MS COCO and can match state-of-the-art edge detection on BSDS500 with fine-tuning. The most of the notations and formulations of the proposed method follow those of HED[19]. 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. key contributions.

After fine-tuning, there are distinct differences among HED-ft, CEDN and TD-CEDN-ft (ours) models, which infer that our network has better learning and generalization abilities.

We present results in the MS COCO 2014 validation set, shortly COCO val2014 that includes 40504 images annotated by polygons from 80 object classes. Moreover, to suppress the image-border contours appeared in the results of CEDN, we applied a simple image boundary region extension method to enlarge the input image 10 pixels around the image during the testing stage. What makes for effective detection proposals? Compared to PASCAL VOC, there are 60 unseen object classes for our CEDN contour detector. A.Karpathy, A.Khosla, M.Bernstein, N.Srivastava, G.E.
